Difference between *Parameter and **Parameter in Python

They both represent unrestricted in number of parameters inputs.

Single Star Parameters

Single Star Parameter would save parameters as tuple.

def fun1(para1, *para2):
    print(para1)
    print(para2)
>>> fun1(1,2,3,4,5)
1
(2,3,4,5)

Double Star parameters

Double Star parameters would save parameters as dictionary.

def fun2(para1, *para2):
    print(para1)
    print(para2)
>>> fun2(1, a=2, c=3)
1
{'a': 2, 'c':3}
