Both A and R are true, and R is the correct explanation of A.
Explanation — In Python, a function can return more than one value at a time by returning multiple values separated by commas. These values are packed into a tuple. If needed, the tuple can be unpacked into separate variables.

The code provided below is intended to swap the first and last elements of a given tuple. However, there are syntax and logical errors in the code. Rewrite it after removing all errors. Underline all the corrections made.
def swap_first_last(tup) if len(tup) < 2: return tup new_tup = (tup[-1],) + tup[1:-1] + (tup[0]) return new_tup result = swap_first_last((1, 2, 3, 4)) print("Swapped tuple: " result)Assertion (A): Positional arguments in Python functions must be passed in the exact order in which they are defined in the function signature.
Reasoning (R): This is because Python functions automatically assign default values to positional arguments.
