Python Range Reverse, For Loop Reverse Range

In this tutorial, we will learn how to use the Python range function in reverse order and use for loops in reverse range.

Usually, we use the range function in a for loop as follows (for example, to generate a list of numbers from 1 to 10):

for num in range(1, 11):
    print(num)

To do the same thing in reverse order, we have to use the third argument (stepping)

For example, to generate a list of numbers from 10 to 1, put 10 in the first field, zero(0) in the second field, and -1 in the third field, as shown in the following code block:

for num in range(10, 0, -1):
    print(num)

The for loop above will print the following:

Let’s look at another example that shows using Python range Function in backwards

for num in range(10, 0, -2):
    print(num)

This time we used -2 in the third argument. This generates a sequence of numbers in steps of two.

Following is another code example that generates a sequence of numbers in reverse order in steps of three:

for num in range(10, 0, -3):
    print(num)

The syntax of the Python range function is range(start, stop, step_count). It generates a list of numbers from the start number up to, but not including the stop number.
