Python Slicing – How to Slice an Array and What Does [::-1] Mean?
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: The start index specifies the index that the slicing starts from. The default is 0.

slice - How slicing in Python works - Stack Overflow
Slicing builtin types returns a copy but that's not universal. Notably, slicing NumPy arrays returns a view that shares memory with the original. This is a beautiful answer with the votes to prove it, but it misses one thing: you can substitute None for any of the empty spaces. For example [None:None] makes a whole copy.

How to Slice Lists/Arrays and Tuples in Python
Python has an amazing feature just for that called slicing. Slicing can not only be used for lists, tuples or arrays, but custom data structures as well, with the slice object, which will be used later on in this article. To understand how the slice function works in Python, it’s necessary for you to understand what an index is.

Array Slicing - Problem Solving with Python
Multiple values stored within an array can be accessed simultaneously with array slicing. To pull out a section or slice of an array, the colon operator : is used when calling the index. The general form is: Where <slice> is the slice or section of the array object <array>. The index of the slice is specified in [start:stop].

How Slicing in Python Works with Examples: A Comprehensive Guide
Python allows you to slice multidimensional arrays using a similar syntax. Let's say we have a 2D array matrix: [4, 5, 6], [7, 8, 9]] If we want to extract the second row [4, 5, 6], we can use the following slice: Similarly, to extract the second column [2, 5, 8], we can use the following slice:
