Python Slicing – How to Slice an Array and What Does [::-1] Mean?
How to Slice an Array in Python. Let's say you want to slice a portion of this array and assign the slice to another variable. You can do it using colons and square brackets. The syntax looks like this: array[start:stop:step] The start index specifies the index that the slicing starts from. The default is 0.

NumPy Array Slicing - W3Schools
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. If we don't pass end its considered length of array in that dimension

How to Slice Lists/Arrays and Tuples in Python
On the other hand, entering the stop parameter is mandatory since it indicates to Python the index to which slicing is supposed to take place. By default, Python will stop the slicing at the value “stop - 1.” In other words, if the stop value is 5 when using the slice function, Python will only return values till the index value is 4.

Python Slicing: 9 Useful Methods for Everyday Coding - Analytics Vidhya
What Are Slicing Operations in Python? Slicing means cutting. Similarly, in Python, it means accessing or extracting a sub-sequence (portion) of a sequence (like strings, lists, tuples, or arrays) by specifying a range of indices. Slicing operations in Python involve using colon operators [:] within the square brackets. The basic syntax involves:

Understanding Array Slicing in Python - AskPython
For both the cases, start is the starting index from which we need to slice the array arr. By default set to 0, stop is the ending index, before which the slicing operation would end. By default equal to the length of the array, step is the steps the slicing process would take from start to stop. By default set to 1. Methods for Array Slicing in Python

slice - How slicing in Python works - Stack Overflow
In Python 2.7. Slicing in Python [a:b:c] len = length of string, tuple or list c -- default is +1. The sign of c indicates forward or backward, absolute value of c indicates steps. Default is forward with step size 1. Positive means forward, negative means backward. a -- When c is positive or blank, default is 0. When c is negative, default is -1.
