#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. Do not worry about error checking the user input unless you want to - you can assume the user types numbers properly. Do not name your variable sum or use the sum() function.

def computepay(hours, rate) :
    if hours >40:
        reg = rate * hours
        otp = (hours -40.0) * (rate * 0.5)
        pay = reg + otp
    else:
         pay = hours * rate
    return pay
sh = input ("enter hours: ")
sr = input ("enter rates: ")
fh = float(sh)
fr = float(sr)
xp = computepay(fh,fr)
print("Pay",xp)
