If you're implying that it's a bug in Python, no it isn't. If you're
trying to understand the bug in your own code, you've come to the
right place :)

Attachments aren't carried on this list; text is better anyway.

Correct. In fact, the strip function does not remove a substring; it
removes a set of characters. It's most commonly used for removing any
whitespace from the ends of a string. It faithfully removed every ".",
"d", "a", and "t" from your string - including the one at the end of
"text".

If you know for sure that the name WILL end with ".data", you can
simply ask Python to remove the last five characters:

>>> 'cm_text.data'[:-5]
'cm_text'

That may better suit what you're doing.

By the way, you may wish to consider migrating to Python 3, as Python
2.7 is a decade old and not getting any further enhancements.
