I am not sure what you are aiming for. If you just want to collect them for 
reading, http://docs.python.org/library/ is much easier.

If you want to produce documentation of your own modules, you may want to take 
a look at pydoc or epydoc.


If you want to collect the doc strings just for the sake of it, add them in a 
list instead of printing:

docs = []
for x in dir(collections):
    docs.append(x.__doc__)

or in one line:  docs = [x.__doc__ for x in dir(collections)]


if you want to make a single (possibly long string of text from that list, 
join the strings together as in

text = "\n".join(docs)


or all in one line (with a generator to suppress creation of the intermediate 
list):

text = "\n".join(x.__doc__ for x in dir(collections))

I have no idea what you are doing with 'ax' here.
You seem to be adding a module and one of its functions and assign the result 
to ax, an operation I don't understand.

If it is important for you, could you please provide some explanation of what 
you trying to do here?
