Silly but true. It started with trying to figure how to remember it's strip() and not trim(). Then it went downhill from there. -- http://mail.python.org/mailman/listinfo/python-list

Don't use "str" and you won't have anything to remember:
'foo bar baz'.find('spam')
'spanish inquisition'.index('parrot')

But which one raises an exception, and which one returns -1?

The name index implies it returns something you can use as an index to get
at the substring.
In other words you can always assume that the following expression is True
(if it has any value at all) when you use the result of index as an index:
s[s.index(t):].startswith(t)
The name 'find' doesn't really imply anything about the result, so it can
return pretty much any crud such as -1.

Ah, is that what Sion meant by "which way around"? Obviously that was
an ambiguous question, since I thought he was referring to the order of
the arguments.
My answer to the other question, unfortunately, is "I just type one of
them at an interpreter prompt and see which result I get". Much faster
than checking the docs...;-)

That's what I meant (and why I wrote "str." not "string.").

Unfortunately, -1 can of course be used as an index. Mind you, it
would be perverse to expect to find the substring at it.

The returned index always points at the substring, therefore the function which returns a -1 isn't returning an index. Therefore index must be the one which raises an exception. -- http://mail.python.org/mailman/listinfo/python-list

How about this: "index" and "sex" both end with "ex", which is short for "exception".

Genius! I will never perplex myself with string_foo.trim() again. (I do forget)
I recommend this be adopted as a naming standard for Python methods:

Re: Just remember that Python is sexy
Yes,
but we don't want it to get out of hand, like calling it orgy() instead of join().
Or condom() instead of secure().
Or onClimax() instead of onFinished()
