Mark Dickinson added the comment:
What's wrong with:
if not isinstance(data, basestring):
raise TypeError(...)
?
In any case, you appear to be wanting to use assert to check user input.
That's not its intended use; instead, it's there for making debugging
assertions. Bear in mind that when running in optimized mode (with python -O),
Python won't execute those asserts at all. (See
http://docs.python.org/3.4/reference/simple_stmts.html#the-assert-statement for
more.)
I think this should be rejected.
