*args and **kwargs in Python

Answer»

We can pass a variable number of arguments to a function using special symbols called *args and **kwargs.

The usage is as follows:


  •    *args: For non-keyword arguments.

   Example:

# the function will take in a variable number of arguments
# and print all of their values
def tester(*argv):
for arg in argv:
print(arg)
tester('Sunday', 'Monday', 'Tuesday', 'Wednesday')
Output:
Sunday
Monday
Tuesday
Wednesday

  •  **kwargs: For keyword arguments.

   Example:

# The function will take variable number of arguments
# and print them as key value pairs
def tester(**kwargs):
for key, value in kwargs.items():
print(key, value)
tester(Sunday = 1, Monday = 2, Tuesday = 3, Wednesday = 4)
Output:
Sunday 1
Monday 2
Tuesday 3
Wednesday 4
