Question

I cant find the definition for divisor anywhere, for this
divisor = 2
for num in range(0, 10, 2):

Answer 1

you have defined divisor as 2
you have assigned 2 to divisor
divisor in this instance is a 'variable' pointing to the integer 2

Answer 3

Actually what I meant was 'what does divisor mean in the context of the whole loop, which finishes with
print(num / divisor)

Answer 4

the shell is a great place to try things out

Answer 5

That's what I meant, knowing that divisor is simply the number by which the original numbers are divided by, of course its obvious in retrospect !

Answer 6

Actually still not entirely sure about this one

Answer 7

Is ' num in range(0,10,2') refer to range 0 to 10 but every alternate number, then that divide by the divisor, which is 2 ?

Answer 8

pretty much

Answer 9

Thanks

Answer 10

No. When range is called with three arguments, the. first is start value, the second is end value and the third is the step. num in range( 0 , 10, 2 ) will give 0, 2, 4, 6, 8

Answer 11

So the last value is step or stride

Answer 12

When called with three arguments, yes.
