如何解决“迭代器应该返回字符串，而不是字节”

I am trying to import a CSV file, using a form to upload the file from the client system. After I have the file, I'll take parts of it and populate a model in my app. However, I'm getting an "iterator should return strings, not bytes" error when I go to iterate over the lines in the uploaded file. I've spent hours trying different things and reading everything I could find on this but can't seem resolve it (note, I'm relatively new to Django- running 1.5- and python - running 3.3). I stripped out things to get to just the error and ran it like this to make sure it is still there. The error is displayed when executing the line "for clubs in club_list" in tools_clubs_import():I am trying to import a CSV file, using a form
