If that's your experience then you're entitled to it! I sometimes find 
the Python library messy but certainly no more so than Java or other 
languages I have used. Perhaps Ruby is the exception, I've only tinkered 
with it.

Several versions of Python ago. This was changed in Sept 2000.

This is incorrect. Lambdas are syntactic sugar for function definitions. 
There is nothing you can do with lambdas that you could not do with 
regular functions.

That much is true. IMHO it's pretty rarely needed in object oriented 
programming but it is nevertheless true that it is clunky in Python.

I'm having trouble following this bit. It's true that you can't directly 
overwrite a variable in a surrounding context. I don't know that this 
has anything to do with assigning function names to variables or global 
variables or anything. The usual workaround is to mutate an object 
rather than overwriting a variable.

def a():
     state = {}
     def putin(x):
        state["something"] = x
     def getout(x):
        return state["something"]
     return putin, getout

But every example I see of this seems contrived to me. You're trying to 
build a "thing" which has both mutable state and functional behaviour. 
Well, in OO languages we tend to call those things objects.

class a:
     def putin(self, x):
         self.something = x
     def getout(self, x):
         return self.something

Hope that helps.

Just out of curiousity, will there be anybody at this university 
describing the things Python can do better than Ruby? It sounds like the 
professor is not knowledgable enough to do that. Perhaps he wants you to 
present both sides?
