An integrated development environment (IDE) refers to a software application that offers computer programmers with extensive software development abilities. IDEs most often consist of a source code editor, build automation tools, and a debugger. Most modern IDEs have intelligentcode completion. In this article, you will discover the best Python IDEs currently available and present in the market.

What is an IDE?

  • An IDE enables programmers to combine the different aspects of writing a computer program.
  • IDEs increase programmer productivity by introducing features likeediting source code, building executables, and debugging.

Features of an IDE

Code with Syntax

2.Autocomplete

IDEs are generally really good at anticipating what you’re more likely to type next, making coding significantly faster and simpler.

3. Building Executables

IDE takes care of interpreting the Python code, running pythonscripts, building executables, and debugging the applications.

4. Debugging 

Programmers can quickly identify errors in their code using the debugging tools provided by IDEs in the event that a program does not function as intended.

Let’s examine a few well-known Python IDEs now that you are aware of integrated development environments.

After typing “Hello World,” you simply press the ENTER key on your keyboard.
[lightweight-accordion title=”Read Detail Answer On Where can I run my Python code?”]

If you are planning to enter the world of Python programming, the first and the most essential skill you should learn is knowing how to run Python script and code. Once you grab a seat in the show, it will be easier for you to understand whether the code will actually work or not. To know more about sys.argv command line argument, click here.   

Given that it’s one of the most popular programming languages, Python has a relatively simple syntax, which makes it even simpler for those just starting to learn it. It is also preferred for use in projects involving big data and data science. Obtain certification, learn more about Python programming, and put your newly acquired skills and knowledge to use in the workplace.

In computing, the code is a language that is converted from a human language into a set of ‘words’ that the computer can understand. It is also referred to as a piece of statements together that forms a program. A simple function or a statement can also be considered a code.

On the other hand, a script is a file consisting of a logical sequence of instructions or a batch processing file that isinterpreted by another program instead of the computer processor.

In simple terms, a script is a simple program, stored in plain file text which contains Python code. The code can be directly executed by the user. A script is also called a top-level-program-file

A module is an object in Python with random attributes that you can bind and reference.

Is Python a Programming Language or a ScriptingLanguage?

In essence, all scripting languages are thought of as programming languages. Programming languages are compiled, whereas scripting languages are interpreted, and this is the main distinction between the two.

Since they move more slowly than programming languages, scripting languages frequently follow them. They have less access to a computer’s native capabilities because they only operate on a portion of the programming language.

Given that it functions as both a compiler and an interpreter, Python can be referred to as both a scripting language and a programming language. The same way Java and C interpret bytecodes, a standard Python compiler can translate Python code into those bytecodes.

However, considering the historical relationship between the general-purpose programming language and the scripting language, it will be more appropriate to say that Python is a general-purpose programming language that works nicely as a scripting language too.

The PythonInterpreter

The Interpreter is a layer of software that works as a bridge between the program and the system hardware to keep the code running. A Python interpreter is an application that is responsible for running Python scripts.

The Python Interpreter works on the Read-Eval-Print-Loop (REPL) environment.

  • Reads the command.
  • Evaluatesthe command.
  • Prints the result.
  • Loops back and process gets repeated.

The interpreter terminates when we use the exit() or quit() command otherwise the execution keeps on going.

A Python Interpreter runs code in two ways— 

  • In the form of a script or module.
  • In the form of a piece of code written in an interactive session.

Starting the Python Interpreter

Opening the terminal and using the interpreter from the command line is the quickest way to get it going.

To open the command-line interpreter:

  • On Windows, the command-line is called the command prompt or MS-DOS console. A quicker way to access it is to go to Start menu  Run and type cmd.
  • On GNU/Linux, the command-line can beaccessed by several applications like xterm, Gnome Terminal or Konsole.
  • On MAC OS X, the system terminal is accessed through Applications → Utilities → Terminal

Running Python Code Interactively

One frequently used method is to run Python code through an interactive session. You can test every line of Python code as you go with an interactive session, which is a great development tool for experimenting with the language.

Type python in the command-line or terminal and press the ENTER key on your keyboard to start an interactive Python session.

An example of how to do this on Windows:

C:\users>pythonPython 3.7.2 (tags/v3.7.2:9a3ffc0492, Dec 23 2018, 23:09:28) [MSC v.1916 64 bit (AMD64)] on win32Type "help", "copyright", "credits" or "license()" for more information.>>>

The >>> on the terminal represents the standard prompt for the interactive mode. If you do not see these characters, you need to re-install Python on your system.

The statements you write when working with an interactive session are evaluated and executed immediately:

print('HELLO WORLD!')HELLO WORLD!2 + 35print('Welcome to the world of PYTHON')Welcome to the world of PYTHON 

The only disadvantage is when you close the interactive session, the code no longer exists.

How to Run Python Script by the Interpreter

The term Python Execution Model is given to the entire multi-step process to run Python script.

READ  How do you download Pokemon Fire Red on Android?
  • At first, the statements or expressions of your script are processed in a sequential manner by the interpreter. 
  • Then the code is compiled into a form of instruction set called thebytecode.Basically, the code is converted into a low-level language known as the bytecode. It is an intermediate, machine-independent code that optimizes the process of code execution. So, the interpreter ignores the compilation step when executing the code for the next time.
  • Finally, the interpreter transfers the code for execution.The Python Virtual Machine (PVM) is the ultimate step of the Python interpreter process. It is a part of the Python environmentinstalled in your system. The PVM loads the bytecode in the Python runtime and reads each operation and executes them as indicated. It is the component that actually runs your scripts.
  • How to Run Python Script using Command-Line

    The most sought-after way of writing a Python program is by using a plain text editor. The code written in the Python interactive session is lost once the session is closed, though it allows the user to write a lot of lines of code. OnWindows, the files use the .py extension.  

    If you are at the beginning of working with Python, you can use editors like Sublime or Notepad++ which are easy-to-use or any other text editors.

    Now you need to create a test script. In order to do that, open your most suited text editor and write the following code:

    print('Hello World!')

    Then save the file on your desktop with the name first_script.py or anything you like. Remember you needto give the .py extension only.

    Using python command

    The most basic and easy way to run a Python script is by using the python command. You need to open a command line and type the word python followed by the path to your script file, like this:

    python first_script.pyHello World!

    Then all that’s left to do is press the keyboard’s ENTER key. The words “Hello World!” are displayed on the screen. Congratulations, you’ve just executed your first Python script.

    However, if you do not get the output, you might want to check your system PATH and the place where you saved your file. If it still doesn’t work, re-install Python in your system and try again.

    Redirecting output

    Stream redirection is a procedure found in Unix-like operating systems like Windows. Instead of using the default system output, you can direct your stream’s output to another file format. The output should be saved in a different file for later analysis.

    An example of how you can do this:

    python first_script.py > output.txt

    What happens is your Python script is redirected to the output.txt file. If the file doesn’t exist, it is systematically created. However, if it already exists, the contents are replaced.

    Running modules with the -m option

    Python code is stored in a file known as a module. It enables logical organization of your Python code. It includes runnable code as well as the definition of functions, classes, and variables.

    If you want to run a Python module, there are a lot of command-line options which Python offers according to the needs of the user. One of which is the command 

     python -m <module-name>. 

    It searches the module name in the sys.path and runs the content as

     __main__:
    python -m first_scriptHello World!

    Note that the module-name is a module object and not any string.

    Using Script Filename

    Python scripts are executed by Windows using the systemregisters and file association. The program required to open that specific file is determined by it. All you have to do is type the filename containing the code.

    An example of how to do this using command prompt:

    C:\Users\Local\Python\Python37> first_script.pyHello World!

    On GNU/Linux systems, you need to add a line before the text— #!/usr/bin/env python. Python considers this line nothing but the operating system considers it everything. It helps the system to decide what program should it use to run thefile.

    The character combination #! known as hashbang or shebang is what the line starts with, which is then followed by the interpreter path.

    Finally, to run scripts, assign execution permissions and configure the hashbang line and then simply type the filename in the command line:

    #Assign the execution permissionschmod +x first_script.py#Run script using its filename./first_script.pyHello World!

    However, if it doesnt work, you might want to check if the script is located in your current

    working directory or not. Otherwise, you can use the pathof the file for this method. 

    How to Run Python Script Interactively

    As we have discussed earlier, running Python scripts in an interactive session is the most common way of writing scripts and also offers a wide range of possibilities.

    Using import

    Importing a module means loading its contents so that it can be later accessed and used. It is the most usual way of invoking the import machinery. It is analogous to#include in C or C++. Using import, the Python code in one module gets access to the code in another module. 

    An implementation of the import:

    import first_scriptHello World!

    Only when the module contains calls to functions, methods, or other statements that produce observable output can you see it being executed.

    One important thing to note is that the import option works only once per session. This is because these operations are expensive.

    The Python code file needs to be in both the Python Module Search Path (PMSP) and your current working directory for this method to function properly. The import of modules and packages takes place at the PMSP.

    You can run the code below to know what’s in your current PSMP:

    import sysfor path in sys.path:print(path)
    \Users\Local\Python37\Lib\idlelib\Users\Local\Python37\python37.zip\Users\Local\Python37\DLLs\Users\Local\Python37\lib\Users\Local\Python37\Users\Local\Python37\lib\site-packages

    You’ll get the list of directories and .zip files where your modules and packages are imported.

    Using importlib

    importlib is a module that is an implementation of the import statement in the Python code. It contains the import_module whose work is to execute any module or script by imitating the import operation.

    An example to perform this:

    import importlibimportlib.import_module('first_script')Hello World!<module 'first_script' from '\Users\Local\Python37\first_script.py'>

    importlib.reload() is used to re-import the module since you cannot use import to run it for the second time. Even if you use import after the first time, it will donothing. importlib.reload() is useful when you want to modify and test your changes without exiting the current session.

    The following code shows that:

    import first_script #First importHello World!import first_scriptimport importlib #Second import does nothingimportlib.reload(first_script)Hello World!<module 'first_script' from '\Users\Local\Python37\\first_script.py'>

    However, you can only use a module object and not any string as the argument of reload(). If you use a string as an argument, it will show a TypeError as follows:

    importlib.reload(first_script)
    Traceback (most recent call last):......  raise TypeError("reload() argument must be a module")TypeError: reload() argument must be a module

    Using runpy.run_module() and runpy.run_path()

    ThePython Standard Library has a module named runpy. run_module() is a function in runpy whose work is to execute modules without importing them in the first place. 

    The module is located using import and then executed. The first argument of the run_module() must contain a string:

    import runpyrunpy.run_module(mod_name='first_script')Hello World!{'__name__': 'first_script',    ...'_': None}}

    Similarly, runpy contains another functionrun_path() which allows you to run a module by providing a location.

    An example of such is as follows:

    import runpyrunpy.run_path(file_path='first_script.py')Hello World!{'__name__': '<run_path>',    ...'_': None}}

    Both the functions return the globals dictionary of the executed module.

    READ  What is an example of an program?

    Run Python script Using exec()

    Other than the most commonly used ways to run Python script, there are other alternative ways. One such way is by using the built-in function exec(). It is used for the dynamic execution ofPython code, be it a string or an object code.

    An example of exec() is:

    exec(open('first_script.py').read())Hello World!

    Run Python Script Using py_compile

    py_compile is a module that behaves like the import statement. It generates two functions— one to generate the bytecode from the source file and another when the source file is invoked as a script.

    You can compile your Python script using this module:

    import py_compilepy_compile.compile('first_script.py' '__pycache__\\first_script.cpython-37.pyc' 

    The py_compile generates anew subdirectory named “__pycache__” if it doesn’t already exist. Inside the subdirectory, a Compiled Python File (.pyc) version of the script file is created. When you open the .pyc file, you can see the output of your Python script.

    Running Python Scripts using an IDE or a Text Editor

    In addition to the necessary tools, an integrated development environment (IDE) is a program that enables software developers to create programs in a unified setting.

    You can write, debug, modify, and run your modules and scripts using the Python IDLE, a default IDE of the standard Python Distribution. Other IDEs that let you run your scripts inside their environments include Spyder, PyCharm, Eclipse, and Jupyter Notebook.

    Python scripts can also be executed using well-known text editors like Sublime and Atom.

    If you want to run a Python script from your IDE or text editor, you need to create a project first. Once it is created, add your .py file to it or you can just simply create one using the IDE. Finally, run it and you can see the output on your screen.

    Running Python Scripts from a File Manager

    You only need to double-click on the file icon in a file manager if you want to run your Python script there. After the source code has been made available, this option is primarily used during production.

    However, to achieve this, some conditions must be met:

    • On Windows, to run your script by double-clicking on them, you need to save your script file with extension .py for python.exe and .pyw for pythonw.exe.

    If you are using the command line for running your script, you might likely come through a situation where you’ll see a flash of a black windowon the screen. To avert this, include a statement at the tail of the script — input(‘Enter’). This will exit the program only when you hit the ENTER key. Note that the input() function will work only if your code is free of errors.

    • On GNU/Linux and other Unix-like systems, your Python script must contain the hashbang line and execution permissions. Otherwise, the double-click trick won’t work in a file manager.

    The operating system, the file manager, execution permissions, and file associations are just a few of the limitations and dependencies that come with double-clicking a script to run it, despite the fact that it is a simple process.

    So it is suggested to use this option only after the code is debugged and ready to be in the production market.

    Conclusion

    Working with scripts has its benefits, such as how simple they are to understand and use, how quickly they can be edited and executed, how interactive and functional they are, and so on. They are also employed to simplify the automation of challenging tasks.
