3.1 String Basics

Strings and string literals

  • A string is a sequence of characters, like the text MARY, that can be stored in a variable.
  • A string literal is a string value specified in the source code of a program.
  • The len() built-in function can be used to find the length of a string (and any other sequence type).
  • .split() will break the string into a list
  • end=' ' will stop print() from creating a newline
    • print('Continue bidding?', end=' ')

  • As a sequence type, every character in a string has an index, or position, starting at 0 from the leftmost character.

    • A programmer can access a character at a specific index by appending brackets [ ] containing the index:

    • Negative numbers will make it start from the right side rather than left

Changing String variables and concatenating strings

  • Individual characters of a string cannot be changed, but the string itself can be altered by updating the entire variable.

  • Concatenation: combining strings
