Python source shows lowest defect density

The 2012 Scan Report found an average defect density of .69 for open source software projects that leverage the Coverity Scan service, as compared to the accepted industry standard defect density for good quality software of 1.0. Python's defect density of .005 significantly surpasses this standard, and introduces a new level of quality for open source software. To date, the Coverity Scan service has analyzed nearly 400,000 lines of Python code and identified 996 new defects — 860 of which have been fixed by the Python community.

That's because one line of Python doesn't do much. Ah, the power of FIOC! If I made a Lisp FIOC derivative where only one atom was allowed per line, imagine how few defects there would be!
