Python IDLE is an Integrated Development Environment (IDE) that comes with Python, which can be used to write and execute Python programs. Here are the basic steps for using Python IDLE:

  1. Open Python IDLE. In Windows, you can find the Python folder in the start menu, then choose “Python (version) -> IDLE”. In Mac, you can find IDLE in the applications folder.
  2. In the interactive Shell of IDLE, you can directly input Python code and press Enter to execute it. For example, you can type “print(‘Hello, World!’)” to print “Hello, World!”.
  3. To write a complete Python program, you can either choose “File -> New File” or use the shortcut Ctrl+N to create a new file.
  4. In a new document, you can write multiple lines of Python code. For example, you can input the following code:
def greet(name):
    print('Hello, ' + name + '!')

greet('Alice')
  1. Save the file by choosing “File -> Save” or using the shortcut Ctrl+S. Select a suitable file name and location to save it.
  2. Run the program. Choose “Run -> Run Module” or press the F5 key to run the program. You will see the output results of the program in the Shell window.

This is just the basic usage of Python IDLE, it also has other features such as a debugger and auto-completion. You can find more detailed information in the IDLE’s help documentation.
