I am in process learning Python and normally hang out on the Tutor list, but monitor this one hoping to learn what I can. This thread is of interest to me from the standpoint of trying to understand the Python way of doing things.

Expecting Python to act like C family languages *is* bizarre. I have to admit being surprised by this, too. I am just now studying on how to write my own classes in Python, and have come to realize that doing this is *possible*, but the *surprise* to me is why the language design allowed this to actually be done. > Common Python thought:: "We're all adults here." If you want to override > a builtin within your own namespace, who are we to stop you? I'm surprised that this thought has not been added to the "Zen Of Python", as I see it as more and more recurrent as I continue my studies. What I would like to comprehend is what is the essential mindset of Python? That is, what do I need to understand, so that I am no longer likely to be surprised by discovering new possibilities in Python such as what the current thread is discussing? -- boB
