What to Focus On

  • Strings are sequences of Unicode characters.
  • Single, double, and triple quotes can create strings.
  • Triple-quoted strings can extend across multiple lines.

  • Indexing starts at 0 from the left.
  • Negative indexing starts at -1 from the right.
  • len() gives the string length.

  • Strings cannot be modified after creation.
  • Assigning to a string character raises TypeError.
  • Methods like replace() return a new string.

Common Mistakes to Avoid

The first character in a string has index 1.

A string character can be changed like a list item.

find() and index() behave the same way when a substring is missing.

Memory Tips

String definition and Unicode characters

Python has no separate character data type

Strings as immutable

Positive indexing from left to right
