The defect density in Python programming language code improved to 0.005
defects per thousand lines of code, a new study finds.
The open-source Python programming language has continued to steadily
improve its code quality in recent years and now surpasses that of its open-
source and proprietary peers, according to a study published by development
testing vendor Coverity.
"The Coverity platform is part of the Python build system," Zack Samocha,
senior director of product management at Coverity, told eWEEK. "As their
code changes, a new build is submitted to the Scan service and new defects
are then sent to Python to be fixed."
Coverity's code-scanning system for open-source projects, including Python,
has been in place since 2006, when the effort was first funded by the U.S.
Department of Homeland Security (DHS). The original DHS funding grant was
only for a three-year term, and since its expiration, Coverity has been
funding the open-source code scanning on its own.
According to Coverity, the average defect density across all the open-source
software that it measures is 0.69 defects per thousand lines of code.
Python, which does better than the average, comes in at 0.005 defects per
thousand lines of code. So far in 2013, Coverity's scanning technology has
analyzed more than 396,000 lines of code in the latest builds of Python 3.3.
2. That analysis has led to 181 new defects being identified. For the year
to date, Python developers have already fixed 278 defects.

发帖数: 666 | 2 这个跟Coverity分析Python的能力有关。跟静态语言不一样，Python程序的很多bugs/
defects要runtime才能暴露出来，Coverity不一定对Python程序具备这样的静态分析能
力。这样的比较不见得是公平的。
