@genaiexp Duplicate data entries can skew your analysis and lead to incorrect conclusions. Pandas provides straightforward methods to identify and remove duplicates effectively. The duplicated() function helps you identify duplicate rows in a DataFrame, optionally considering a subset of columns if only specific fields should be unique. Once identified, you can remove these duplicates using the drop_duplicates() method, which retains the first occurrence by default but can be configured to keep the last or even drop all duplicates. It's essential to ensure that removing duplicates doesn't inadvertently remove necessary data, so understanding your dataset's context is crucial. Maintaining data integrity while cleaning necessitates a careful balance, ensuring that your cleansed dataset remains representative of the original data.
