Question

Is there any library in python for duplicate code checker? I use python IDE and I am finding trouble refactoring my code. Are there any python library available which suggest duplicate code in the program/project?

Update: I found clone digger which as per its site,

We have tested Clone Digger on sources of several open-source projects. There are following drawbacks of the current report format:

Differences are highlighted using diff algorithm. This way of
highlighting has nothing common with the abstract syntax tree based
algorithm of comparing sequences of statements for similarity.

Class and function comments are taken into account during the
computation of similarity, but they are not presented in the output.
Therefore some clone pairs can look equal but marked as convergent.

Are there any tools better than this?

Pylint has a check for similar/duplicate code: https://pylint.readthedocs.io/en/latest/technical_reference/features.html#similarities-checker

Usage:

pylint --disable=all --enable=similarities src/yourcode/
