"""Functions for handling Strings

This module provides a few functions for manipulating strings.
This module is intended to prepare you for the first assignment.

The functions included here may include intentional errors."""

def first_inside_quotes(s):
    """Returns: The first substring of s between two (double) quote characters
    
    Example: If s is 'A "B C" D', this function returns 'B C'
    Example: If s is 'A "B C" D "E F" G', this function still returns 'B C'
    because it only picks the first such substring.
