remove duplicate in df ignore one column

Comment

#You've actually found the solution. For multiple columns, subset will be a list.

df.drop_duplicates(subset=['City', 'State', 'Zip', 'Date']) 

#Or, just by stating the column to be ignored:

df.drop_duplicates(subset=df.columns.difference(['Description']))
