Key Topics to Revise

1

1. Basics of Strings

  • A string is a consecutive sequence of characters enclosed in single quotes or double quotes.
  • Python treats single quotes the same as double quotes.
  • A string may contain letters, numbers, special characters, and backslashes.
2

2. Escape Sequences and Multiline Strings

  • An escape sequence starts with a backslash and does not represent itself directly.
  • Escape sequences are used to insert special characters or characters that are difficult to type directly.
  • '\t' is a tab, '\n' is a newline, and '\r' is a carriage return.
3

3. String Indexing and Traversing

  • Indexing in Python starts from zero, so the first character has index 0.
  • Positive indexing starts from the left side.
  • Negative indexing starts from the right side, with -1 for the last item.
4

4. String Operators

  • Strings can be joined using the + operator.
  • The * operator repeats a string a given number of times.
  • The membership operators in and not in check whether a substring exists within a string.
