Use io.BytesIO and io.StringIO

In python3 StringIO and cStringIO are gone. In their place are
io.BytesIO and io.StringIO. They are somewhat different in that they are
not separated on implementation, but on the type they emulated. BytesIO
works like the bytes class (str in python 2), while StringIO works like
the str class (unicode in python2).
