Calculates the difference of a DataFrame element compared with another element in the DataFrame default is element in previous row Parameters periods int default 1 Periods to shift for calculating difference accepts negative values axis 0 or index 1 or columns default 0 Take difference over rows 0 or columns 1 Pandas DataFrame diff pandas 2 1 4 documentation. The following code shows how to count the number of matching values between the team columns in each DataFrame count matching values in team columns df1 team isin df2 team value counts True 3 False 2 Name team dtype int64 We can see that the two DataFrames have 3 team names in common and 2 team names that are different Using the example data from the original ion The first step is to concatenate the DataFrames horizontally with the concat function and distinguish each frame with the keys parameter df all pd concat df set index id df2 set index id axis columns keys First Second df all It s probably easier to swap the column
