I have two sublists with the same 0 index. I’d like to merge them into one sublist, as shown here. Driving me crazy!
This method works in python, I’ll try to see if I can do a node version:
datalist = IN[0]
data_dict = dict()
for sub in datalist:
if sub[0] in data_dict:
[data_dict[sub[0]].append(d) for d in sub[1:]]
else:
data_dict[str(sub[0])] = sub[1:]
newdata = []
for i,sub in enumerate(datalist):
try:
newdata.append(data_dict.pop(str(sub[0])))
newdata[i].insert(0, sub[0])
except KeyError:
continue
OUT = newdata

That would be great. I haven’t used Python code yet.
It is pretty easy if you just need to add in one node. Just create a python script node, double click it to enter, delete everything that is premade in it, and copy and paste what I typed above into it.

Nick, this is awesome. It works. I haven’t used the nodes List.Deconstruct or List.GroupByKey before. Need to get up to speed on “keys”. Very educational - thank you!
I tried the Python code, but got 0 for a result. I copied and pasted as you suggested. Hmm. Nick_Boyts solved it using nodes, so I’m good to go. Thanks for the input.
FYI 0 is the default output. You probably missed something in the code.
It looks like you double clicked the title of the block, not the block itself. Double click the beige part.
