I have the for-loop:
L=[1,2,3,4]
I want, that the code below works:
for i in range(1,len(L)):
if i%2==0:
L.remove(L[i])
How can I do this? Many thanks.

What do you mean "I want, that the code below works"? – mgilson Sep 12 '16 at 16:11

So you want even indexed elements? Comprehensions are your friend.
L = [e for i,e in enumerate(L) if i % 2]

@mgilson that's something I've never seen before - really neat. Is there a name for that style? – Tyler Sebastian Sep 12 '16 at 16:12

I hope veingrow will google what enumerate does and what is list comprehension. – Dinesh Pundkar Sep 12 '16 at 16:13

@TylerSebastian It's called the `step` or the `stride`, an optional argument for list slicing. – Matt Sep 12 '16 at 16:16

@TylerSebastian Its just a part of list slicing. The third term (if any) defines the step size – Ma0 Sep 12 '16 at 16:16
