Naming the variable 

Naming variables may seem to be a minor topic, but trust us, adopting a good habit of proper naming will save you a lot of time and nerves down the road. Do your best to name variables wisely and consistently. Ambiguous names will make code extremely hard to read, understand, and debug, for no good reason.

• You cannot use reserved words: False, class, finally, is, return, None, continue, for, lambda, try, True, def, from, nonlocal, while, and, del, global, not, with, as, elif, if, or, yield, assert, else, import, pass, break, except, in, or raise.
