In Python, the name variable is a built-in variable that is used to store the name of a module, function, class, or method. Its purpose is to provide a way to access the name of an object programmatically, without hardcoding it.

        For example, consider the following Python function:

def greet(name):
    print(f"Hello, {name}!")

        In this function, the name variable is used to store the name of the person being greeted. However, the name variable can also refer to the name of the function itself, which can be useful in certain situations. For example, you can use the __name__ attribute of a function to access its name:

print(greet.__name__)  # Output: "greet"

        Similarly, the __name__ attribute of a module contains the name of the module, which can be useful for debugging and introspection purposes. For example, you can use the __name__ attribute of a module to check if it is being run as the main program:

if __name__ == "__main__":
    # Run this code if the module is being run as the main program
    print("Hello, world!")

        In summary, the name variable in Python is a built-in variable that is used to store the name of an object, such as a module, function, class, or method. It can be accessed using the __name__ attribute of the object, and is useful for debugging and introspection purposes.
