do:

return str(primarykeys)

Also there are Python modules for just this. Here is the very first link 
from Google:

http://pypi.python.org/pypi/python-json

I have used this one personally and have been very satisfied with it. 
There is another one (CJSON?) which is similar, but written in C, for 
when performance may be an issue.

Hope this helps.
