Clone Digger is a duplicate code detection tool which supports the Python language. It works on the abstract syntax tree level. Discovered clones can differ in small subexpressions; comments and whitespaces are ignored. The report on found clones is written to HTML in a two-column format with the differences highlighted. Clone digger is platform-independent. It has been tested on several open-source projects and the results indicated that about 12% of their code is covered by clones.
