Hi Rasmus,

Yes that's really annoying. Happens whenever one types outside of the main scope it seems! There are two really useful Python commands which can help you a lot when figuring out which methods or attributes an item has, what's in a namespace and so on:

dir(itemTocheck)

help(itemToCheck)

So if you have a GH datatree called myTree, you would go:

print dir(myTree)
print help(myTree)

Hope that helps.

/Anders

Hi Anders. 

Thanks. Yeah it is pretty annoying. I haven't been able to find out when it happens yet. Cause sometimes it comes back. But I'll try and remember about the main scope. 

Thanks for the advice. That is a great help.

Ps. another topic: do you know if it is possible to keep the path structure of a data tree when doing list operations within each branch?

Say cull list within a tree. If I have a tree[{4};{5};{6}], then after cull or similar operations I get tree[{0;1},{0;2}, {0;3}].

I can fix it with a pathMapper, but it would be nice I i didn't have to.

Do you mean if you are operating on datatrees within a Python component? If so I think it would need some example file to better understand what's going on. In general I would advice you to stick to using Python lists in your classes and defs within the Python script. Then, if you need it, you can write some small utility scripts to convert a GH Datatree to a nested Python list and back again for the input/output of the component.

I have also been trying to find out how to remove a branch from a tree, similar to list.pop(i). or del list[i];

-thanks

You can use the RemovePath() method. See attached file. Hope that helps..
