How to extract parameters from a list and pass them to a function call [duplicate]

by

You can unpack a tuple or a list into positional arguments using a star.

def add(a, b, c):
    print(a, b, c)

x = (1, 2, 3)
add(*x)

Similarly, you can use double star to unpack a dict into keyword arguments.

x = { 'a': 3, 'b': 1, 'c': 2 }
add(**x)
