Why is this code not an infinite loop?

[psi2kgcm]

Hi,

Why is following code not infinite loop when I am setting the loop's counter variable i to 0 before it comes to an end?

def f():
	for i in range(3):
		for j in range(3):
			input(str(i)+str(j))    # just for seeing output one by one ...
		i = 0
	return

Please give academic style answers.

this is for loop, not while loop. There is no condition to check and decide to continue or not the loop, i.e. the value of i is irrelevant if there will be next iteration or not. you are free to use/assign new value to i in the loop body, e.g.

for i in range(3):
    i *= 2
    print(i)
