This PR fixes a few minor errors my IDE found. For instance, twice "except exception" was used, when "exception" should be capitalized, and once, ceil() was called instead of math.ceil. There's also a case of sys.exit() being called when sys hadn't been imported. Finally, there's one grammar change, going from "don't" to "doesn't" to agree with the subject of the sentence.
