Selecting unique observations in a pandas data frame

2024/11/17 16:21:34

I have a pandas data frame with a column uniqueid. I would like to remove all duplicates from the data frame based on this column, such that all remaining observations are unique.

Answer

There is also the drop_duplicates() method for any data frame (docs here). You can pass specific columns to drop from as an argument.

df.drop_duplicates(subset='uniqueid', inplace=True)
