Exercises - Conditional Execution

Exercise 1 – Write a program that give the employee 1.5 times the hourly rate for hours worked above 40 hours.

hours = raw_input("Enter hours: ")

payrate = raw_input("Enter rate: ")

h=float(hours)

br=float(payrate)

if h>40:

    extra = h-40

    base = h-extra

    sallary = (base*br)+(extra*br*1.5)

else:

    extra = 0

    base=0

    sallary = h*br

print "Pay: " + str(sallary)

Exercise 2 – Rewrite your pay program using try and except so that your program handles non-numeric input gracefully by printing a message and exiting the program.

hours = raw_input("Enter hours: ")

payrate = raw_input("Enter rate: ")

try:

    h=float(hours)

    br=float(payrate)

    if h>40:

        extra = h-40

        base = h-extra

        sallary = (base*br)+(extra*br*1.5)

        print "Pay: " + str(sallary)

    else:

        extra = 0

        base=0

        sallary = h*br

        print "Pay: " + str(sallary)

except:

    print 'Error, please enter numeric input'  

Exercise 3 – Write a program to prompt for a score between 0.0 and 1.0. If the score is out of range print an error. If the score between 0.0 and 1.0, print a grade using the following table:

uservalue=raw_input("Enter score: ")

try:

    x = float(uservalue)

    if x<0 or="" x="">1.0:

        print "Bad score"

    else:

        if x<=1.0 and x>=0.9:

            print "A"

        elif x<=0.89 and x>= 0.8:

            print "B"

        elif x<=0.79 and x>= 0.7:

            print "C"

        elif x<=0.69 and x>= 0.6:

            print "D"

        elif x<0 .6:="" o:p="">

            print "F"

        else:

            print "Bad score"

except:

    print "Bad score"
