So, in PY101, when explaining how to build code, Mae will insert commands like !=. I have no idea what that means, and when I ask, she will tell me and then tell me we will go over it in future courses. I have been through all 4 weeks and never once has != has ever been discussed. Why bring it up now, before it is taught, and will it ever be taught or is it one of those things you have to find for yourself?
