How do I loop backward using indices in Python

Question

I want to loop from 100 to 0, how do I do it?

for i in range (100,0) #this is not working

Answer 1

Hi,

You can make use of negative indices to start from back:

for i in range(100):
    k = 100 - i
    print(k)

Or You can use:

for i in reversed(range(101)):
    print(i)

Both will give same output that is 100 to 0
