In python, can we decrement the control variable in for loop?

Question

From what I have observed, the for loop in Python doesn't need a separate code to increment the control variable but how do I decrement the control variable in the loop. Can I do it without writing a separate code for it?

Answer 1

You just need a negative step for example...
#30->21
for i in range(30, 20, -1):
print(i)
