# 4.6 Write a program to prompt the user for hours and rate per hour using input to compute gross pay. Pay should be the normal rate for hours up to 40 and time-and-a-half for the hourly rate for all hours worked above 40 hours. Put the logic to do the computation of pay in a function called computepay() and use the function to do the computation. The function should return a value. Use 45 hours and a rate of 10.50 per hour to test the program (the pay should be 498.75). You should use input   to read a string and float() to convert the string to a number.

def computepay(a,b):
    if a < 40 :
        return a*b
    else :
        return (40*b + (a - 40)*b*1.5)

hrs = input("Enter Number of Hours worked:")
rt = input('Enter the required rate per hour: ')
hours = float(hrs)
rate = float(rt)
print( computepay(hours,rate) )
