Removing Duplicates

To remove the duplicate rows, simply use function drop_duplicates(). To change the current dataframe, add inplace=True.


              123
            
new_data = data.drop_duplicates() # data is not modified
# or
data.drop_duplicates(inplace=True) # data is modified

Tarefa

The planets dataset is given to you. Remove the duplicates and then check the new shape of dataframe. Compare it with the original shape.

Note that dataframe may have only distinct records, in this case, the shape will remain the same.
