Ahem! Quite. That was what I actually intended to post!

But having seen the other posts suggesting using future 
I had a rethink.

I don't think either float() or the "3.0" approach will help the 
OP because I suspect he is trying to eval a string stored 
in a variable. In that case the "import future" trick is probably 
the only solution that will work, short of parsing the string and 
doing the division without using eval...

HTH,
