Python - Pandas Duplicates Finding and Filling

Basic Program 1:

Detailing:

From the above example we can see that Row number 2, Row number 4 is returning True means those were all the row seems duplicated from some other existing data.

Note:

Above example only second occurrence of the data as duplicates.

Basic Program 2:

Detailing:

From the above example, you can see that i have added new keyword called

keep = False

Keep = False will make sure that True is returned no matter whether it is on the First occurrence or any other occurrences.

Note:

So when any combination is duplicated entire combination will return TRUE.

Basic Program 3:

Detailing:

From the above example, you can see that i have added new keyword called

keep = "last"

Keep = 'last' will make sure that True is returned n the First occurrence . Which is quite opposite to the one which we saw first in this article.

Note:

"last" needs to be enclosed in either single or double quote. Because "last" is not keyword like False in the another example.

Basic Program 4:

Detailing:

If you cross verify rest of the above program with this program , it is little different in the output.

This program returns only the duplicated items from the dataset .

Notes:

All the above example, program returns entire dataset and returns True for the duplicates on First Occurrences or Second Occurrences or Both .
