 From what I can tell no mod_python 2.7.X has the get() method. At least
2.7.10 doesn't and there was no 2.7.X version after that.

Instead of get() you can use [] subscript but you will have to catch the
exception if key isn't present.

Don't wait for the get() method to be added as no more work is being  
done
on mod_python 2.7.X branch. The method does exist in 3.X branch though.
