Question

In python 3,

1. Write a program that takes a number of credit hours and returns a classification as follows:

29 credits or less: freshman; 30-59 credits: sophomore; 60-89 credits: junior; 90+ credits: senior.

2. Use a loop to valid input such that users can only enter positive numbers.

3. Use a loop to allow the user to keep entering credit hours and receiving classifications until they quit.

All code must be in a function. I suggest the following structure:

returnValidatedInput – gets user input, validates, and returned validated input

printWelcome – tells the user about the program

main – lets the user continue until the quit, calls appropriate helper functions.

Sample run:

Hi and welcome to the undergraduate classification program.

Would you like to continue (Y/N)? Y

Enter the number of credits earned: 94

Classification: Senior

Would you like to continue (Y/N)? Y

Enter the number of credits earned: -80

Invalid input. Enter the number of credits earned: 80

Classification: Junior

Would you like to continue (Y/N)? N

Have a great day!

Please find the answer below:

I have mentioned all the details in the comments.

Please take care of indentation in code, I am attaching an image of the code as well for your reference.

#welcome finction
def printWelcome():
print("Hi and welcome to the undergraduate classification program.")
#get the input from user and return the valid input
def returnValidatedInput():
value = int(input("Enter the number of credits earned: "))
while(value < 0):
print("Invalid input.")
value = int(input("Enter the number of credits earned: "))
return value

#classification of value
def classification(value):
if(value<=29):
return "Freshman"
if(value<=59):
return "Sophomore"
if(value<=89):
return "Junior"
return "Senior"

#main function to ask user until user want
def main():
#call welcome
printWelcome()
#get intial input from user
user_in = input("Would you like to continue (Y/N)? ")
#loop till user says yes
while(user_in == 'Y'):
#get value from user
value = returnValidatedInput()
#classify value and print result
print("Classification: " ,classification(value))
#check if user wants to continue
user_in = input("Would you like to continue (Y/N)? ")
#goodbye message
print("Have a great day!")
  
#call to main function
main()

Code:
