Best way to convert a list into function call arguments?

4.7.4 Unpacking Argument Lists

The reverse situation occurs when the arguments are already in a list or
tuple but need to be unpacked for a function call requiring separate
positional arguments. For instance, the built-in range() function
expects separate start and stop arguments. If they are not available
separately, write the function call with the *-operator to unpack the
arguments out of a list or tuple:

>>> range(3, 6)             # normal call with separate arguments
[3, 4, 5]
>>> args = [3, 6]
>>> range(*args)            # call with arguments unpacked from a list
[3, 4, 5]
