string.find has always been kind of a wart in Python; that's why
they're getting rid of it. For testing for the presence of a
substring, use the in operator:
if "something" in check:
do(somethingElse)
When you need the position of a substring, using the index methods:
i = check.index("something")
index returns an exception of the substring is not there, so no need
to worry about what it returns.
Finally, it really won't kill you to do this:
if check.find("something") >= 0:
do(somethingElse)
