Both left and right joins return all the records from one of the tables (despite having no matches). Is there kind of join that will return records that have matching values in both tables.

To perform an inner join, use the .merge() method with the how = 'inner' parameter. For instance, let's perform an inner join of previously used two tables.

# Importing library import pandas as pd # Loading data data1 = pd.read_csv('https://codefinity-content-media.s3.eu-west-1.amazonaws.com/f2947b09-5f0d-4ad9-992f-ec0b87cd4b3f/section5/data1.csv') data2 = pd.read_csv('https://codefinity-content-media.s3.eu-west-1.amazonaws.com/f2947b09-5f0d-4ad9-992f-ec0b87cd4b3f/section5/data2.csv') # Perform a left join df_res = data1.merge(data2, on = 'id', how = 'inner') print(df_res)
