How do I compare columns in different data frames? I would like to compare one column of a df with other df's. The columns are names and last names. I'd like to check if a person in one data frame is in another one.
If you want to check equals values on a certain column let's say Name you can merge both Dataframes to a new one: 

mergedStuff = pd.merge(df1, df2, on=['Name'], how='inner')
mergedStuff.head()


I think this is more efficient and faster then whereif you have a big data set
