Probably my most annoying coding blind spot…

Do you have that one thing that you have to constantly look up?

In python, to replace elements of a string, there are two operators.  One is a strictly linear search, the other uses regular expressions.  The regexp call to replace part of a string with another string is sub, and the string call to replace a part of a string with another string is replace.

I get these backward all the flamin’ time, and it drives me insane.  I use both of these every day, why the Hell can’t I remember which is which?

I'd try to remember this this way:

"regex starts with r. The call that uses it should too! But they got it WRONG and it DOESN'T start with r."
