If I copy a value from the bottom list and paste it at the top of the column right next to its duplicate value, it recognizes the new duplicate that I have just created, but wont recognize the same number from the top list as a duplicate. I'm finding duplicates based on the x,y,z coordinates as these should be unique locations so I use df.dropduplicates (subset 'x', 'y', 'z', inplaceTrue) to remove any duplicates from the data frame. It appears that the values I pasted from one list don't seem to match the values from the other list when I paste them in. I checked for trailing and leading spacesĪll the cells are formatted the same (as text) I tried re-pasting everything as Values Only I have manually verified that duplicates exists However, you can create rules to handle custom-object records that duplicate an.
