Overview

String are a Python sequence of characters. Strings are immutable, a string cannot be changed in-place. Python 3 supports the Unicode standard, so Python 3 strings can contain characters from any written language in the world.

Quotes

String literals can be declared using four type of quotes: sigle quotes '...', double quotes "...", triple single quotes '''... and triple double quotes """...""".

Single and Double Quotes

The [] Operator and String Slices

The [] operator can be used to read strings from the sequence, but not modify the sequence. Because strings are immutable, an attempt to change a character at a specific position in string will throw an TypeError exception:

s = 'abc'
s[0] = 'x'
[...]
TypeError: 'str' object does not support item assignment
