searching for __doc__ from the interactive cmd line

Greetings from a tyro Python enthusiast.
I like it that you can get some documentation at the interactive command
line by printing __doc__ strings, so I thought I'd automate things a bit.
Being a lazy & stupid beginner I don't always know which module contains the
method I'm interested in, so I thought it would be cool to do something
method = findMethodInList(globals().values(), methodName)
if method != None and hasattr(method, "__doc__"):
print method, method.__doc__
print "Sorry, no __doc__"
Or something like that - I hope you get the idea. Then I could type:
That's when the trouble starts. I don't know if it's actually
myModule.myThingy or myOtherModule.myThingy or maybe there isn't even a
myThingy at all... that's the whole reason I'm writing this. And neither
does the interpreter: if myThingy isn't in scope right now, I get an
exception before my function ever gets called.
So I try:
And off I go. But is there a way to set a global exception handler of some
sort when I'm running at the interactive command line so that I don't have
to quote myThingy? I told ya I was lazy ;-)
Thanks for any info. I'm assuming someone's already done something like
myThingy(spam, eggs) -> string
Concatenates the arguments, what should be strings, sends them to the
synthesizer, then returns a rude message in a string
Any pointers to source?
