django - Using StringIO With Python 3.4 -

so i'm using python 3.4 code isn't working. importing cstringio , i've fixed it's getting unexpected error.

heres error:

and here code:

def create_thumbnail(self): if not self.image: homecoming pil import image io import stringio, bytesio django.core.files.uploadedfile import simpleuploadedfile import os thumbnail_size = (280, 600) django_type = self.image.file.content_type if django_type == 'image/jpeg': pil_type = 'jpeg' file_extension = 'jpg' elif django_type == 'image/png': pil_type = 'png' file_extension = 'png' image = image.open(stringio(self.image.read())) image.thumbnail(thumbnail_size, image.antialias) temp_handle = stringio() image.save(temp_handle, pil_type) temp_handle.seek(0) suf = simpleuploadedfile(os.path.split(self.image.name)[-1], temp_handle.read(), content_type=django_type) self.thumbnail.save( '%s_thumbnail.%s' % (os.path.splitext(suf.name)[0], file_extension), suf, save=false )

the traceback telling stringio expects string providing bytes. utilize bytesio instead os stringio.
