 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  
on mod_python 2.7.X branch. The method does exist in 3.X branch though.
