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, unicode, list, tuple, bytearray, buffer, xrange section, and also the
string-specific methods described in the String Methods section.
To output formatted strings use template strings or the % operator
described in the String Formatting Operations section. Also, see the
re module for string functions based on regular expressions.
