Indexing with python

[hussein99]

Hello Everyone,
I am trying to put this python script in the node and it giving me this error because of the indexing.

Does any one have idea how can I solve this problem? (It’s taking the RowID as an index but it is from the type string, if I use the RowID node to reffer it to another integer column it wont work also)

Hi @mohini1329, as the others have already suggested, you should make sure that each row in the Pandas DataFrame has a unique index. Dropping/resetting the index is not the best option though, because KNIME uses the RowID (which is equal to the DataFrame index) to identify rows when you select / highlight individual cells in your data. If you reset the index, then this row identification will no longer work. The best solution would be to let the index of all values in your input table as they…
