How Replace Empty list?

[f.saeedian]

Hello freind. How can Replace Empty list with another list in dynamo?

[bvs1982]

Pretty sure there is ReplaceItemAtIndex node.

[sovitek]

yeah guess clockwork and archilabe have nodes for that could probably help

[bvs1982]

[f.saeedian]

I do it but return null

[f.saeedian]

that

[bvs1982]

The node from Archilab works for me.

NB
I was in 2023. You are in 2022 i guess.

[f.saeedian]

Thanx. I do but emply still is hear

That’s because your list levels need adjusting.

[bvs1982]

It works without the Levels .

He wired the wrong node / List in to replacement.
I didn’t notice that at first .

Too early in the morning.

Was thinking you could probably do it with design script too…

Something like this… but my designscript absolutely sucks and I can’t make it work.

@Alien

but my designscript absolutely sucks and I can’t make it work.

I guess we need @Vikram_Subbaiah for that .

Super easy with Python tho:

[sovitek]

and an alternative way maybe

[f.saeedian]

I have problem hear

[Alien]

The indents are important in Python.
Use the Tab key or use 4 spaces.

Each indent must be the same. So either use tabs or 4 spaces.

[f.saeedian]

Thanx a lot its work

[f.saeedian]

Actualy I want to use this script for list beleow but it still is empty

[Alien]

You’d have to use nested loops for that… or maybe some recursive function.

With your particular problem I’d suggest you use a ready made node because you can set the list levels easily.

@f.saeedian
Out of curiosity. Why use Python and not the nodes?
Do you know what you did wrong in your original graph?
