Answer 1

Answer:

# while loop to take input until user want to exit
while True:
# taking input from the user
userString = input("Ehter input String: ")
if userString == "q":
exit(0)
# spliting the input by comma
strings = userString.split(',')
# checking whether comma is present in the string or not
if ',' not in userString:
print("Error: No comma in string")
print("Try Again..")
continue
# checking user has entered exactly two string or not
if len(strings) > 2:
print("More then two strings are entered.")
print("Try Again..")
continue
# printing the words
print("First word: " + strings[0].strip())
print("Second word: " + strings[1].strip())
