(2) Report an error if the input string does not contain a comma. Continue to prompt until a valid string is entered. Note: If the input contains a comma, then assume that the input also contains two strings. (2 pts)

Error: No comma in string.

Enter input string: Jill, Allen

Enter input string:
Jill, Allen
First word: Jill

while True:

        break
    if name.find(',') == -1:
        print("Error: No comma in string.")
    else:
        words = name.split(",")
        first = words[0].strip()
        last = words[1].strip()
        print("First word: " + first)
        print("Second word: " + last)
