(original) (raw)

I knew it didn't exist by that name, but couldn't know whether there was another function that did the same thing or technique to make it not needed.

So I couldn't know whether it's new or not, therefore I couldn't know whether it should be on python-ideas or not.�

You see, Antoine, \*you\* know that it's better asked on python-ideas because you know it doesn't exist in Python, therefore it's an idea for an addition. However, when a person like me asks this question, he does not know whether it exists or not, so he can't know whether he's proposing a new idea or whether it's something that exists under a different name or whether that's something that can't exist because of some unknown reason that the asker didn't think of.


Now that I know it doesn't exist, I'll ask this on python-ideas.

I think there might be a language issue here because you originally said "Why is there no�str.rreplace in Python?" which shows you already knew it didn't exist. Did you mean to say you wanted to know *why* it didn't exist?


Even in that case, if searching for \[python str.rreplace\] didn't turn up anything then chances are there was no proposal, which makes it a new idea and thus belongs on python-ideas. Basically the rule of thumb is anything considered new goes to python-ideas first.
