How to Reverse a Range in Python
To create a reverse range in Python pass a negative value as the third argument of the
range() function. This value is the number of steps to take between each number in a range.
To demonstrate this, let's create a list of numbers from 0-5 in descending order.
numbers = range(5, 0, -1) for n in numbers: print(n)
5 4 3 2 1
Reverse an Existing Python Range
To reverse an existing range, use the Python
reversed() function. Store the result in a new variable as it will not modify the original range.
numbers = range(1, 5) numbers_desc = reversed(numbers) for n in numbers_desc: print(n)
4 3 2 1
