Receiving Tuples and Dictionaries as Function Parameters

If we need to take variable number of arguments in the function, we can use the * and ** prefix to indicate receiving tuple and dictionary.

>>> def powersum(power, *args):
... '''Return the sum of each argument raised to the specified
power.'''
...     total = 0
...     for i in args:
...         total += pow(i, power)
...         return total
...
>>> powersum(2, 3, 4)
25
>>> powersum(2, 10)
