From the Python 2 documentation
[[https://docs.python.org/2/library/functions.html#basestring|basestring()]]:
This abstract type is the superclass for str and unicode. It cannot be
called or instantiated, but it can be used to test whether an object is an
instance of str or unicode. isinstance(obj, basestring) is equivalent to
isinstance(obj, (str, unicode)).
New in version 2.3.
This is not available in Python 3.
The tool 2to3 changes {{{basestring}}} into {{{str}}} (the only string
type in Py3).
There are 27 effected modules.
