6.6 Warm up: Parsing strings (Python 3)

(1) Prompt the user for a string that contains two strings separated by a comma. (1 pt)

• Examples of strings that can be accepted:
  • Jill, Allen
  • Jill , Allen
  • Jill,Allen

Ex:

Enter input string: Jill, Allen

(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)

Ex:

Enter input string: Jill AllenError: No comma in string.Enter input string: Jill, Allen

(3) Using string splitting, extract the two words from the input string and then remove any spaces. Output the two words. (2 pts)

Ex:

Enter input string: Jill, AllenFirst word: JillSecond word: Allen

(4) Using a loop, extend the program to handle multiple lines of input. Continue until the user enters q to quit. (2 pts)

Ex:

Enter input string: Jill, AllenFirst word: JillSecond word: AllenEnter input string: Golden , MonkeyFirst word: GoldenSecond word: MonkeyEnter input string: Washington,DCFirst word: WashingtonSecond word: DCEnter input string: q
