Hi Lauren,
What happens here is that "processString2(parameter)" executes at the
point you define the dictionary. So myDictionary[string2] is None
because that's what your method returns.
What you need to do is put an actual function in there, instead of a
function call.
Here's a toy example:
>>> def say_hello():
... print 'Hello world!'
...
>>> myDict = { 1:say_hello } # note: no () here!
>>> myDict[1]
<function say_hello at 0x4638f0>
>>> myDict[1]() # now I use () to call the function.
Hello world!
Hope this helps!
