How to call a nested function in Python

In Python, you can call a nested function by first calling the outer function that contains the nested function definition and then calling the nested function from within the outer function.

You can define nested functions with arguments and call them accordingly.

def outer_function():
    print("This is the outer function.")

    def nested_function(arg):
        print("This is the nested function with argument:", arg)

    # Call the nested function from within the outer function
    nested_function("Hello from outer function")

# Call the outer function
outer_function()

Output /

This is the outer function.
This is the nested function with argument: Hello from outer function

In this example, nested_function takes an argument arg, and it is called with the argument "Hello from outer function" from within outer_function.
