Parsing strings (Python 3)

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 Allen

Error: 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, Allen

First word: Jill

Second 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, Allen

First word: Jill

Second word: Allen

Enter input string: Golden , Monkey

First word: Golden

Second word: Monkey

Enter input string: Washington,DC

First word: Washington

Second word: DC

Enter input string: q
