Are you sure that you are running python 3.x in each environment? I'm
not familiar with Komodo, so I can't help you there, but in python
v2.x input attempts to evaluate the values you enter. raw_input, on
the other hand returns your data as a string. In python 3, input was
removed and raw_input's name was changed to input.
See if you have two different versions of python on your system.
