You have a function called "csv()" in your code.

So when you go csv.blahbittyblob, you've overriden your imported module
called "csv" with the function called "csv", python then tries to look up
the attribute blahbittyblob and can't find it. it then throws an error.

Change your csv function to be csvx() or _csv or something other than csv
