Diff between two dataframes in pandas

Question

I have two dataframes both of which have the same basic schema. (4 date fields, a couple of string fields, and 4-5 float fields). Call them df1 and df2

Answer 1

Try this:

diff_df = pd.merge(df1, df2, how='outer', indicator='Exist')

diff_df = diff_df.loc[diff_df['Exist'] != 'both']

You will have a dataframe of all rows that don't exist on both df1 and df2.
