How to delete multiple items on a list containing a specific character

[the_carole24]

Hey guys, I'm new to Snap! so I'd appreciate the help!

I have an alphanumeric list containing "a1", "a2", "a3", "a4", "a5", "a6", "a7", "a8", "a9", "a10", "a11", "a12", "b1", "b2", and etc.

I want to be able to delete any item containing the number 4 and greater. So the output I want is "a1", "a2", "a3". Is there any way to do this?

So the output I want is "a1", "a2", "a3".

You want b1, b2, and b3 also, right?

(This isn't your homework, is it? It'd be a nice homework problem.)

Actually, this is better:

Yeah. I didn't want to assume exactly one letter at the beginning, but if that's the case, I agree your way is simpler.

Thanks everybody!

Which library did you get the "join input list" block?

[bh]

It's the regular JOIN block. Hold the input expression over the left and right arrowheads at the end of the block and you'll see a red halo covering all the input slots. Let go when you see the red halo and it becomes an INPUT LIST.

ok got it, thanks!!

I find it easier to remove all the inputs oin the join block, then drop the reporter on it.

[warped_wart_wars]

That does make it easier. Also keep the JOIN separate from other blocks so you don't accidentally drop the block into the wrong one.

[ego-lay_atman-bay]

If you get rid of all the inputs, then it won't try to drop into the last one.

[warped_wart_wars]

No... the block you're dropping into JOIN might end up in a block the JOIN is in.

I only do it if I can't get it into the input list.
