With the for loop we can execute a set of statements, once for each item in a list, tuple, set etc. Home » Python » How to increment a variable on a for loop in jinja template? To decrement the index value inside the for loop in Python, we can use the range function as the third parameter of this function will be negative.By making the step value negative it is possible to decrement the loop counter. In this tutorial, we will learn how to loop in steps, through a collection like list, tuple, etc. You will notice 4 spaces before the print function because Python needs an indentation.
