python expression on an "attribcreate" node.

[Symbolic]

Hi,

I would like to create a string attribute storing the name of the previously connected node.

If I go with the `opinputpath(".",0)` solution... this returns the whole path... I can go into stripping out the last part... but I would like to do that with the python way...

I usually have my python commands on a button, never had a python to be evaluated on a node. How does that work?

Thanks.

Came across this the other day you need to set a keyframe to have a python expression evaluate in a parameter. Look out for double quotes though when you an a keyframe to an existing expression as the get added automatically, you need to remove them.

Thanks. Actually I was suggested a better way for this. Just to share it... You need to switch the node's expression language to "python" firtst. Then "Edit expression". Type the python code in and hit apply or accept and the box is green. No need for a keyframe. Because setting a keyframe really messes up that box... really...

When it goes green that is the keyframe getting added though isn't it?

I guess so. But if you just type it in. It just does not get green. Then when you set a keyframe... it gets green but the syntax gets messed up as well. Maybe it is just for me. I found it cleaner to be done with the expression editor.

Sorry, I totally forgot to mention about the actual python code to list the inputs. It is:

hou.pwd().inputs()[0].name()

Thanks.
