Can I use cStringIO the same as StringIO?

I did this:

import cStringIO.StringIO as StringIO

And I realize I've been using it everywhere. Is that fine? Is it treated the same as StringIO?

Solution

  • They are not the same. cStringIO doesn't correctly handle unicode characters.

    >>> StringIO.StringIO().write(u'\u0080')

>>> cStringIO.StringIO().write(u'\u0080')
Traceback (most recent call last):
  File "<stdin>", line 1, in <module>
UnicodeEncodeError: 'ascii' codec can't encode character u'\x80' in position 0: ordinal not in range(128)
