How Can I Unpack a Tuple to Pass its Elements as Individual Function Arguments in Python?

Expanding Tuples as Function Arguments

In Python, when invoking functions with tuples as arguments, the asterisk operator (*) can be used to unpack the tuple, allowing its elements to be passed as individual arguments.

Suppose you have a function myfun defined as follows:

def myfun(a, b, c):
    return (a * 2, b + c, c + b)

To call myfun using a tuple some_tuple = (1, "foo", "bar"), use the following syntax:

myfun(*some_tuple)

The asterisk unpacks some_tuple, resulting in:

myfun(1, "foo", "bar")

This call returns the tuple (2, "foobar", "barfoo"), as desired. This technique is known as "argument unpacking" and is particularly useful when a function expects a variable number of arguments.
