What is the process for removing rows that exist in another dataframe?

Python

Hey everyone, I am recently learning about data cleaning. Can anyone guide me about how to remove rows present in another DataFrame in Pandas. As I am bit confused about which method is to use. And what are the steps that I have to follow while writing my code.

Hey @nimrah , you can achieve this task simply by converting the column values of DataFrames to tuples using the Pandas ‘apply()’ method by passing the tuple parameter. This creates a set-like object that can be used with set operations. Then:

  • Compute the set difference between the two sets of tuples using the - operator.
  • Use the resulting set of tuples to filter the original data frame.
