Python utility to extract differences between two pandas dataframes

import pandas_diff as pd_diff

import pandas as pd

# Create two example dataframes
df_infinity = pd.DataFrame([
                {"hero" : "hulk" , "power" : "strength"},
                {"hero" : "black_widow" , "power" : "spy"},
                {"hero" : "thor" , "hammers" : 0 },
                {"hero" : "thor" , "hammers" : 1 } ] )
df_endgame = pd.DataFrame([
                {"hero" : "hulk" , "power" : "smart"},
                {"hero" : "captain marvel" , "power" : "strength"},
                {"hero" : "thor" , "hammers" : 2 } ] )

# Get differences, using the key "hero"
df = pd_diff.get_diffs(df_infinity ,df_endgame ,"hero")
