CD4Py is a code de-duplication tool for Python programming language. It detects near and exact duplicate source code files. To train a machine learning model on source code files, it is essential to identify and remove duplicate source code files from the dataset.

A simple Python3 tool to detect similarities between files within a repository - platisd/duplicate-code-detection-tool

It finds duplicate code across large software systems, using compiler-accurate parsing to find matches guided by the language syntax (AST matching), ignoring changes in whitespace and linebreaks. It will find exact duplicates, and near-miss duplicates.

Mar 8, 2022 · When I have multiple .py files, I can use pylint --enable=duplicate-code to check for duplicate code between different files. But how can I check if there is duplicate code within one single Python file?
