Hi everyone,
I am taking a python class and I'm stuck in an exercise.
what am i doing wrong? Can anyone try to run it? Thanks so much!
#Description:Input validation and while loops.
import random
def main(): #main function need in all programs for automated testing
#your program goes here
print()
print("This program will help us practice input validation and while
loops.")
print("The user will be asked to enter two numbers which will both be
validated. ")
print("The sum of the numbers will then be displayed in a complex print
statement ")
print("and the user will be asked if they would like to run the program
again."
)
print()
print()
while True:
FirstNumber = input ("Please enter the first number: ")
if FirstNumber.isdigit ():
FirstNumber = int(FirstNumber)
break
else:
print ("Invalid response. Please enter a whole number. " )
while True:
SecondNumber = input ("Please enter the second number: " )
if SecondNumber.isdigit():
SecondNumber= int(SecondNumber)
break
else:
print("Invalid response. Please enter a whole number." )
print()
print (str(FirstNumber) + " + " + str(SecondNumber)+ " = " +
str(FirstNumber + SecondNumber))
print()
while True:
ans= input('Would you like to run the program again (Y/N) : ')
if ans== 'Y' or ans== 'N':
break
else:
print(" lnvalid response. Please answer with 'Y' or 'N' ")
if ans== 'N':
break
