Python slicing is a computationally fast way to methodically access parts of your data. In my opinion, to be even an intermediate Python programmer, it's one aspect of the language that it is necessary to be familiar with. Important Definitions To begin with, let's define a few terms:
There's the != (not equal) operator that returns True when two values differ, though be careful with the types because "1" != 1.
