#EXERCISE1
#rewrite your pay computation with time-and-a-half for overtime and create a function called computepay which takes 2 parameter (hours and rate)

def computePay():

   The program take hours and rate, and calculate the ordinary payment and extra payment if apply.
   Extraordinary payment applies only if hours per week exceed 40 hours, otherwise ordinary payment is applying.
   The program does not recognize the numbers as string, please enter only numbers
