You can do this in multiple ways. in Shell script
sort <filename> | uniq -c If you have to use Python, then the faster way to do it would be to load the csv into a Pandas dataframe, which should allow you to use dataframe.duplicated() If you don't want to use pandas then you can loop through the csv and create a set or hashmap with the row as the key and count as the value Hope this helps.
