How can you merge two DataFrames in Pandas based on a common column, ensuring that only the matching rows are included in the result?

  • Using the concat() function
  • Using the join() function with the on parameter
  • Using the merge() function with the how='inner' parameter
  • Using the merge() function with the how='outer' parameter
To merge two DataFrames based on a common column and include only the matching rows, you should use the merge() function with the how='inner' parameter. This performs an inner join and includes only rows with matching keys in both DataFrames.
