Slicing arrays. Slicing in python means taking elements from one given index to another given index. We pass slice instead of index like this: [start:end]. We can also define the step, like this: [start:end:step]. If we don't pass start its considered 0.
A slice object can represent a slicing operation, i.e.: a[start:stop:step] is equivalent to: a[slice(start, stop, step)] Slice objects also behave slightly differently depending on the number of arguments, similar to range(), i.e. both slice(stop) and slice(start, stop[, step]) are supported.

Learn how to use slicing to extract and assign data to sequence types in Python. Understand the syntax, bounds, step value, and indices method of slicing.
Array Slicing is the process of extracting a portion of an array. With slicing, we can easily access elements in the array. It can be done on one or more dimensions of a NumPy array.
