What is range function in Python?

In this tutorial, we will learn about the Python range () function with the help of examples. The range () function returns a sequence of numbers between the give range. Note: range () returns an immutable sequence of numbers that can be easily converted to lists, tuples, sets etc. The start and step parameters in range () are optional.

How do you decrement a range in Python?

That means that you’ll be decrementing by 2 for each loop: You got a range of numbers that were each smaller than the preceding number by 2, the absolute value of the step you provided. The most Pythonic way to create a range that decrements is to use range (start, stop, step). But Python does have a built-in reversed function.

What is a range function in JavaScript?

When the user call range () with one argument, the user will get a series of numbers that starts at 0 and includes every whole number up to, but not including, the number that the user has provided as the stop. In this example, we are printing the number from 0 to 5. We are using the range function in which we are passing the stopping of the loop.

How to get reverse range of numbers in Python?

You can use the following two ways to get the reverse range of numbers in Python. Use a negative step value in a range () function to generate the sequence of numbers in reverse order. For example, range (5, -,1, -1) will produce numbers like 5, 4, 3, 2, and 1. I.e., you can reverse a loop by setting the step argument of a range () to -1.
