Title
Body
I want to create a count of unique values from one of my Pandas dataframe columns and then add a new column with those counts to my original data frame. I've tried a couple different things. I created a pandas series and then calculated counts with the value_counts method. I tried to merge these values back to my original dataframe, but I the keys that I want to merge on are in the Index(ix/loc). Color Value Red 100 Red 150 Blue 50 I want to return something like: Color Value Counts Red 100 2 Red 150 2 Blue 50 1
