String Services

The modules described in this chapter provide a wide range of string manipulation operations.

In addition, Python’s built-in string classes support the sequence type methods described in the Sequence Types — str, bytes, bytearray, list, tuple, range section, and also the string-specific methods described in the String Methods section. To output formatted strings, see the String Formatting section. Also, see the re module for string functions based on regular expressions.
