Hmm. Well, I can see your point -- after all, if are "explaining" but
your audience is not understanding, are you really explaining? Okay,
looking in the dictionary...
ex⋅plain –verb (used with object)
1. to make plain or clear; render understandable or intelligible: to
explain an obscure point.
2. to make known in detail: to explain how to do something.
un⋅der⋅stand –verb (used with object)
1. to perceive the meaning of; grasp the idea of; comprehend: to
understand Spanish; I didn't understand your question.
2. to be thoroughly familiar with; apprehend clearly the character,
nature, or subtleties of: to understand a trade.
3. to assign a meaning to; interpret: He understood her suggestion as a
4. to grasp the significance, implications, or importance of: He does
not understand responsibility.
For me, at least, it boils down to this feeling that understanding is
not a True/False item, but more of a scale (like all the the numbers
between 0.0 and 1.0 [not including 1.0 of course -- this *is* Python!
;)]). As a personal example, decorators are not that difficult to grasp
-- you take your function and wrap it in another function; but what you
can do with them! They are truly impressive once your understanding
And at the end of the day (or this thread, whichever comes first ;)
Python is awesome, and that's what counts.
