• PEP 594: 从标准库中删除死电池
  • PYTHON.ORG

"This PEP proposed a list of standard library modules to be removed from the standard library. The modules are mostly historic data formats (e.g. Commodore and SUN file formats), APIs and operating systems that have been superseded a long time ago (e.g. Mac OS 9), or modules that have security implications and better alternatives (e.g. password and login)."
