Select items from an array #python #shorts

Do you want to quickly select every nth element in a Python array? No problem, arrays in Python have built-in 3S property (aka slice notation), where you can specify start, stop and step to filter items in an array. Syntax is pretty simple, array[start:stop:step]. Implicitly if you don’t specify the property, Python will default to the largest unfiltered value and stop value is not included. Default stop value is length of the array, default start value is 0 and default step value is 1. This video shows a few examples on a sample array.
