In this section you learned that:

• Functions can have more than one parameter:

def volume(a, b, c):
    return a * b * c

• Functions can have default parameters (e.g. coefficient):

def converter(feet, coefficient = 3.2808):
    meters = feet / coefficient
    return meters

print(converter(10))

Output: 3.0480370641306997

Arguments can be passed as non-keyword (positional) arguments (e.g. a) or keyword arguments (e.g. b=2 and c=10):

def volume(a, b, c):
    return a * b * c

print(volume(1, b=2, c=10))

• An *args parameter allows the  function to be called with an arbitrary number of non-keyword arguments:

def find_max(*args):
    return max(args)
print(find_max(3, 99, 1001, 2, 8))

Output: 1001

• An **kwargs parameter allows the function to be called with an arbitrary number of keyword arguments:

def find_winner(**kwargs):
    return max(kwargs, key = kwargs.get)

print(find_winner(Andy = 17, Marry = 19, Sim = 45, Kae = 34))

Output: Sim
