you can prove it by opening a terminal, typing "python", hitting enter, then copying my line and verifying the result.

whats your sticking point?

sum([j*2 for j in range(0, 11/2)]) ?

It's not right. It doesn't give you the value 10, as you'd "expect".

0

2

2+4 = 6

2+4+6 = 12

if you sum even numbers, starting from 0, "10" is not a possible result. i dont know what youre trying to do there.

I mean the list: [j*2 for j in range(0, 11/2)] Does not give you the item "10" in the list.

So it skips 10...

yea, because 5 is the end of the range.

if you do sum(range(0,10,2)), 10 isn't reached either.

why are we having this discussion?

Yeah, but if you write "end_range" I'd expect that to be the end range. So your implementation should actually be something like:

[j2 for j in range(0, (11+1)/2)]

Your code is wrong.

sum(range(0,11,2)) works as expected, [j*2 for j in range(0, (11)/2)] does not.

congrats.

What?

You seem like you have issues.
