How Can I Unpack Tuples to Pass Arguments to a Function in Python?

Expanding Tuples into Arguments

When working with functions that accept multiple arguments, you may encounter scenarios where you need to provide these arguments as a collection, such as a tuple. This article explores how to use the * (star or asterisk) operator to unpack tuples and expand them into the individual arguments required by a function.

Consider the following function:

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

Suppose you have a tuple named some_tuple containing values that you want to pass to myfun. To do this, you can use the * operator as follows:

myfun(*some_tuple)

In this expression, the * operator unpacks the some_tuple into individual arguments that are passed to myfun. If some_tuple contains values (1, "foo", "bar"), the function call would be equivalent to:

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

This would result in the tuple (2, "foobar", "barfoo") being returned by myfun. By using the * operator, you can conveniently pass a collection of arguments to a function that expects individual values.
