Learning Objectives

  • Accept any number of positional arguments with *args
  • Accept any number of keyword arguments with **kwargs
  • Unpack arguments when calling functions

*args for Positional Arguments

Use *args to accept any number of positional arguments as a tuple.

def total(*numbers):
    result = 0
    for n in numbers:
        result += n
    return result

print(total(1, 2, 3))
print(total(10, 20))

Course Example: Filtering Arguments

This function prints only non-integer arguments passed to it.

def print_arguments(*args):
  for value in args:
    if type(value) == int:
      continue
    print(value)

print_arguments(1, "hello", 2, "world", 3.14)
