What does """ means in python?

[Sam]

For string, one uses "" to represent string. Below is a code fragment that uses 
""" instead.

cursor.execute("""SELECT name, phone_number 
                  FROM coworkers 
                  WHERE name=%s 
                  AND clue > %s 
                  LIMIT 5""",
               (name, clue_threshold))
