Answer:
The program in Python is as follows:
print("Welcome to sorting program")
print("1. Title")
print("2. Rank")
print("3. Date")
print("4. Start")
print("5. Likes")
while(True):
choice = input("Enter a choice between 1 and 5 only: ")
if choice.isdigit() == True:
if(int(choice)>=1 and int(choice)<=5):
print("You entered valid choice", choice)
break;
else:
print("You have not entered a number between 1 and 5. Try again")
else:
print("You entered an invalid choice")
Explanation:
This prints the header
print("Welcome to sorting program")
The next 5 lines print the instructions
print("1. Title")
print("2. Rank")
print("3. Date")
print("4. Start")
print("5. Likes")
The loop is repeated until it is forcefully exited
while(True):
This prompts the user to enter a choice
choice = input("Enter a choice between 1 and 5 only: ")
This checks if the choice is a digit
if choice.isdigit() == True:
If yes, this checks if the choice is between 1 and 5 (inclusive)
if(int(choice)>=1 and int(choice)<=5):
If yes, this prints valid choice and the choice entered
print("You entered valid choice", choice)
The loop is exited
break;
If the choice is out of range
else:
This prints the error and tells the user to try again
print("You have not entered a number between 1 and 5. Try again")
If choice is not a digit
else:
This prints invalid choice
print("You entered an invalid choice")
