How is the preservation of positional arguments during function calls implemented in Python?

In Python, positional arguments in a function call are preserved and passed in the order they were specified. This is implemented through the mechanism of packing and unpacking arguments using *args.

For example:

def func(*args):
    for i, arg in enumerate(args):
        print(f"Argument {i}: {arg}")

func(10, 20, 30)

Here, *args collects all positional arguments into a tuple, maintaining their order. When calling the function, positional arguments are passed exactly in the order they are specified, ensuring the sequence is preserved.
