The type of 1 is 'int' and the type of int is 'type'. It is telling you that you are trying to add an integer to a type object. > here is the entire section of the module that i imported that's giving > me the trouble. Why is it giving the TypeError? It would really help to see *your* code and the *complete* traceback. Can you figure out where _dx and _dy are coming from? They don't seem to be assigned in the code you show here.
