Exercise 3.1 Rewrite your pay computation to give the employee 1.5 times the hourly rate for
hours worked above 40 hours.
'''
a="Enter Hours:"
b=raw_input(a)
c="Enter Rate:"
d=raw_input(c)
if int(b)>40:
    print "Pay1",40*float(d)+(int(b)-40)*(float(d)*1.5)
else:
    print "Pay2",int(b)*float(d)

'''
Exercise 3.2 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. The following
shows two executions of the program:
'''
a="Enter Hours:"
try:
    b=raw_input(a)
    int(b)
except:
    print "Error, please enter a numeric input"
c="Enter Rate:"
try:
    d=raw_input(c)
    float(d)
    if int(b)>40:
            print "Pay1",40*float(d)+(int(b)-40)*(float(d)*1.5)
    else:
            print "Pay2",int(b)*float(d)
except:
    print "Error,please enter a numeric input"

Exercise 3.3 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 is between 0.0 and 1.0, print a grade using the following table
'''
a=raw_input('Enter score:')
#program stops when you type finish
while(a!='finish'):
    if(float(a)>=1.0 or float(a)<=0.0):
        print 'Bad Score'
    if float(a)==0.9:
        print 'A'
    elif float(a)==0.8:
        print 'B'
    elif float(a)==0.7:
        print 'C'
    elif float(a)==0.6:
        print 'D'
    elif float(a)<0.6:
        print 'F'
    a=raw_input('Enter your score:')
