Or you could just actually try it out, given that you're at the interactive prompt.

That's that dir(the_object) or dir(the_class) thing...

Well, I guess this probably needs decent docs in Python, at least, but anyway...

Or just try it out! Yes, there are sometimes cases when you don't want to try it out, but then you wouldn't be running tests in such cases either. That would be a fairly specialised field of software development, I would imagine.

Well, I wouldn't necessarily disagree with that, given some people's way of using them (type two characters, slap Ctrl-Space, press F2 or whatever over and over again), but I can see that for languages like C++ you really need your IDE to remind you of the specification for some parameterised class, and then when you're calling the next_element method, you need reminding again about the parameter types ("What am I iterating over again? Oh, it's element<xzgr_spec_type<PQS_n, gqb_itype>>, of course!").
Yes, Python could be nicer even with some non-evaluating introspection mechanisms, and some IDEs even provide that, but you seem to be talking about the topic like some hypothetical exercise rather than what the experience of developing in Python is actually like. Shit or chocolate? A cheap shot indeed!
