Variable names are not unique and 'cellID_obs' is not defined

UPDATE: Ran my updated code on jupyter notebook with the solutions listed above and here is the outcome... I do not know why we need to make the gene names different since we are looking only at cell ID but I did it any way (not shown).

Loading loom files and packages

loom file index:

loading seurat files (NOTE: manually changed Cell IDs) and attempting to merge

Changing the code to the suggestion in #9 produced the following error:

Anyone know how to proceed?

In case anyone else runs into this issue, I just manually went in and created a new .CSV with just the one column. That way, if python is selecting the whole df, there is no way it selects anything else...kind of a long way round since the code is supposed to do it for me but I couldn't find why it was not cooperating.
