Python code has the lowest defect density

The Python code has the lowest density of bugs, just 0.005 per thousand lines of code, according to the Coverity company, which provides development testing services. Industry-accepted standards are 1 per thousand lines of code defects, code defect density less than 1.0, which is considered high-quality code. According to the 2012 Open source Code Scan report, the average defect density of open source code is 0.69, while Python is 0.005.
