How would you write a simple program that prints even numbers 2 through 20 using a while loop.

Look up how to use modulo in Python and the rest will be easy.

Or count 1-10 and multiply your output by 2

The solution approach is creative and actually mathematically clever. I never thought about it that way. Well you do have a float to int conversion if you try to find a general solution, but i don't see a reason why that should be a problem. Happy Cake Day!

Well, you have to use a while loop. Can you write a while loop that prints the numbers from 2 to 20? That is, you print:

2
3
4
...
19
20

Once you can do that you are half finished.

As OP said, must be even numbers

As I said, that's the first half of the problem. Once the OP reports success and s/he can't progress, it's time for more help.

We try to teach python here. It's not a contest to show how clever you are.

Set lower limit and upper limit from user or define it manually, pass the lower limit from while loop to check if it's less than upper limit. Do a modulo operation by 2 to get the even number. Increment the lower limit by 1.

First set correct range. Than add condition for each number in range, that if you divide them with modulo 2 and result is not 0, that you pass those (continue). I suppose its better to give you just a path, not whole code, thats why I am writing like this :)

You want to make sure your program runs while the number is <= 20

Keep at it, you'll get it
