cold fjord writes: eWeek reports, "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.
