Learning goals

• Build strings with single, double, and triple quotes.
• Index characters with s[0], s[-1], and positions in between.
• Slice strings with s[:3], s[3:], s[2:5], and use a step like s[::2] or s[::-1].
• Use escape sequences \n, \t, \", \', \\.
• Remember that strings are immutable — you cannot change one character in place.
