Week 5 - Assignment 3.1

Write a program to prompt the user for hours and rate per hour using input to compute gross pay. Pay the hourly rate for the hours up to 40 and 1.5 times the hourly rate for all hours worked above 40 hours. 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.

Program

hrs = input("Enter the number of Hours worked: ")

rt = input ('Enter the require rate per hour: ')

hours = float(hrs)

rate = float(rt)

if hours < 40 :

print(hours*rate)

else :

print(40*rate + (hours - 40)*rate*1.5)

Assignment 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:

Score Grade

>= 0.9 A

>= 0.8 B

>= 0.7 C

>= 0.6 D

< 0.6 F

If the user enters a value out of range, print a suitable error message and exit. For the test, enter a score of 0.85.

Program

score = float( input("Enter your Score: ") )

if 0 <= score <= 1 : # if 0 <= score and score <= 1: is also correct

if score >= 0.9 :

print('A')

elif score >= 0.8 :

print('B')

elif score >= 0.7 :

print('C')

elif score >= 0.6 :

print('D')

else:

print('F')

else:

print('Enter a valid score')

quit()

Week 6 - Assignment 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.

Program

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) )

Week 7 - Assignment 5.2

Write a program that repeatedly prompts a user for integer numbers until the user enters 'done'. Once 'done' is entered, print out the largest and smallest of the numbers. If the user enters anything other than a valid number catch it with a try/except and put out an appropriate message and ignore the number. Enter 7, 2, bob, 10, and 4 and match the output below.

Program

smallest_no = None

largest_no = None

while True:

inp = input('Enter a number: ')

try:

num = int(inp)

except:

if inp == 'done' or inp == 'Done' or inp == 'DONE' :

break

else:

print('Invalid input')

continue

if smallest_no is None:

smallest_no = num

largest_no = num

elif num < smallest_no :

smallest_no = num

elif num > largest_no :

largest_no = num

print('Maximum is',largest_no)

print('Minimum is',smallest_no)
