2. create a sample dataframe with duplicate rows:
3. use `drop_duplicates()` to remove duplicate rows based on all columns:
4. specify columns for identifying duplicates:
5. specify keeping the last occurrence of duplicates:
6. specify keeping the first occurrence of duplicates:
in the above examples, `subset` allows you to specify the columns to consider for identifying duplicates, while `keep` lets you specify whether to keep the first occurrence, last occurrence, or drop all duplicates.
