Introduction
Idle download is a term that refers to downloading Python and IDLE (Integrated Development and Learning Environment) together. Python is a popular programming language that lets you work quickly and integrate systems more easily. IDLE is a simple but powerful graphical user interface (GUI) that comes with Python. It allows you to write, edit, run, debug, and test Python code in a convenient way.
Idle download is useful because it gives you everything you need to start coding in Python without any hassle. You don't have to worry about finding, installing, or configuring other tools or libraries. You can just download one package and get started right away. Idle download also has some benefits over other Python development environments, such as:
It is cross-platform: it works mostly the same on Windows, Linux, and macOS.
It is coded in 100% pure Python, using the tkinter GUI toolkit.
It is easy to use: it has a simple and intuitive interface that is suitable for beginners and experts alike.
It is free and open source: you can use it for any purpose without any restrictions or fees.
How to Download Python and IDLE
The first step to use idle download is to download Python and IDLE from the official website. Here are the steps to follow:
Go to and find the latest version of Python for your operating system. You can also choose a different version if you have specific requirements.
Click on the download link and save the file to your computer. The file name will vary depending on your operating system and version. For example, for Windows 10 and Python 3.11.4, the file name will be python-3.11.4-amd64.exe.
Run the downloaded file and follow the instructions on the screen. You will have some options to customize your installation, such as choosing the installation directory, adding Python to your PATH environment variable, or installing additional features. You can also choose the default settings if you are not sure what to do.
Wait for the installation to finish and close the installer.
To verify that Python and IDLE are installed correctly, open a command prompt or terminal window and type python --version. You should see something like this:
Python 3.11.4
If you see an error message or a different version number, something went wrong with your installation. You might need to reinstall Python or check your PATH environment variable.
To run IDLE, you can either type idle in your command prompt or terminal window, or you can find it in your Start menu or Applications folder. You should see a window like this:
This is the interactive shell window, where you can type and execute Python commands. You can also use it to test and debug your code.
How to Use IDLE for Python Development
Now that you have downloaded and installed Python and IDLE, you are ready to use them for your Python development. Here are some basic steps to follow:
How to create, edit, save, and run Python files in IDLE
To create a new Python file in IDLE, you can either go to File > New File or press Ctrl+N on your keyboard. You will see a new window like this:

This is the editor window, where you can write, edit, save, and run your Python code. You can also open an existing Python file by going to File > Open or pressing Ctrl+O on your keyboard.
To save your Python file, you can either go to File > Save or press Ctrl+S on your keyboard. You will be prompted to choose a name and location for your file. Make sure to use the .py extension for your file name.
To run your Python file, you can either go to Run > Run Module or press F5 on your keyboard. Your code will be executed in the interactive shell window and you will see the output there. You can also use the interactive shell window to interact with your code after running it.
How to use the interactive shell window for testing and debugging code
The interactive shell window is a powerful tool for testing and debugging your code. You can use it to enter and execute Python commands, expressions, and statements. You can also use it to inspect and modify the values of variables, functions, and objects in your code.
To enter a command, expression, or statement in the interactive shell window, you can type it after the >>> prompt and press Enter on your keyboard. For example:
>>> print("Hello, world!") Hello, world! >>>> x = 10 >>>> x + 5 15 >>>> def square(n): ... return n 2 ... >>>> square(4) 16
To inspect or modify the value of a variable, function, or object in your code, you can use the built-in functions dir(), type(), help(), and print(). For example:
>>> dir() ['__annotations__', '__builtins__', '__doc__', '__loader__', '__name__', '__package__', '__spec__', 'square', 'x'] >>>> type(x)
>>>> help(square) Help on function square in module __main__: square(n) # returns the square of n >>>> print(square.__doc__) # returns the square of n
To debug your code, you can use the built-in function input() to pause the execution of your code and ask for user input. You can also use the built-in function breakpoint() to set a breakpoint in your code and enter the debugger mode. For example:
# This is a simple program that asks for two numbers and prints their sum num1 = int(input("Enter the first number: ")) num2 = int(input("Enter the second number: ")) breakpoint() # This will pause the execution and enter the debugger mode sum = num1 + num2 print("The sum is", sum)
When you run this program in IDLE, you will see something like this:
This is the debugger mode, where you can inspect and modify the values of variables, functions, and objects in your code. You can also use some commands to control the execution of your code, such as:
c: continue execution until the next breakpoint or the end of the program.
n: execute the next line of code.
s: step into a function call.
r: return from a function call.
q: quit the debugger mode and stop the execution of the program.
How to customize the appearance and behavior of IDLE
Another feature of IDLE is that you can customize its appearance and behavior to suit your preferences and needs. You can change the font size, color scheme, indentation, and other options for the editor and the interactive shell windows. You can also enable or disable some features, such as code completion, call tips, auto-indentation, and syntax highlighting.
To customize IDLE, you can go to Options > Configure IDLE or press Alt+C on your keyboard. You will see a window like this:
This is the configuration window, where you can choose from different tabs to change different settings. For example:
Fonts/Tabs: You can change the font name, size, and style for the editor and the interactive shell windows. You can also change the indentation width and whether to use spaces or tabs for indentation.
Highlights: You can change the color scheme for the editor and the interactive shell windows. You can choose from some predefined themes or create your own custom theme.
Keys: You can change the keyboard shortcuts for various commands and actions in IDLE. You can choose from some predefined key sets or create your own custom key set.
General: You can change some general options for IDLE, such as the startup window, the initial size and position of windows, the autosave interval, and the default source encoding.
