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. This will always return True and "1" == 1 will always return False, since the types differ. Python is dynamically, but strongly typed, and other statically typed languages would complain about comparing different types. There's also the else clause:
In Python 3, your example range (N) [::step] produces a range object, not a list. To really see what is happening, you need to coerce the range to a list, np.array, etc.
