Python - os.popen和subprocess.Popen有什么区别？

1 个解决方案

The os process functionality is considered obsolete. os进程功能被认为是过时的。 The subprocess module was introduced in Python 2.4 as a unified, more powerful replacement for several older modules and functions related to subprocesses. subprocess模块是在Python 2.4中引入的，它是对几个与子进程相关的旧模块和函数的统一，更强大的替代品。 They are listed here : 它们列在这里：

os.system
os.spawn*
os.popen*
popen2.*
commands.*

os.popen was deprecated in Python 2.6 (but, interestingly, it is not deprecated in Python 3, where it is implemented in terms of subprocess.Popen ). os.popen是在Python 2.6（但是，有趣的是，它不是在Python 3，其中弃用弃用它在以下方面实现subprocess.Popen ）。 There is a paragraph in the documentation on how to replace it with subprocess.Popen . 文档中有一段关于如何用subprocess.Popen替换它的段落。
