No, nothing wrong with that.
But:
* Function names ending in `-mode' suggest mode functions.
The convention for predicates is to use suffix `p' or
`-p'. See (elisp) `Coding Conventions'.
* You probably want the doc string to say that it returns
non-nil if... Just saying that something tests something
doesn't tell you how to understand the test result. ;-)
* If you just want to check for those two modes then it
is more correct to check membership:
(memq major-mode '(python python-mode))
That rules out returning non-nil for, say, `pythonesque'.
