""" Example 
>>> my_wrapper()
wrapper recieved: 0 args and 0 kwargs
a: 6 + b: 8 = 14

>>> my_wrapper(a=5, b=10)
wrapper recieved: 0 args and 2 kwargs
a: 5 + b: 10 = 15

>>> my_wrapper('hello')
wrapper recieved: 1 args and 0 kwargs
a: 6 + b: 8 = 14

>>> my_wrapper('hello', a=3)
wrapper recieved: 1 args and 1 kwargs
a: 3 + b: 8 = 11
