subprocess.call(args, *, stdin=None, stdout=None, stderr=None, shell=False) # Run the command described by args. # Wait for command to complete, then return the returncode attribute. 在下面的示例中,完整的命令将为ls -l#!/usr/bin/env python import subprocess subprocess.call(["ls", "-...
The undocumented endtime argument to subprocess.Popen.wait() should not have been exposed and is hopefully not in use; it is deprecated and will mostly likely be removed in Python 3.5. The strict argument of HTMLParser is deprecated. The plistlib readPlist(), writePlist(), readPlistFromBytes...
P_WAIT, 'cp', L, os.environ) Availability: Unix, Windows. spawnlp(), spawnlpe(), spawnvp() and spawnvpe() are not available on Windows. spawnle() and spawnve() are not thread-safe on Windows; we advise you to use the subprocess module instead. 在3.6 版更改: 接受一个 类路径...

基础初级 1.基本使用 输入输出 print()打印到屏幕 输入函数:输入的数会是字符串格式,口号中双引号引起来可以添加提示信息。 input() raw_input() 进入和退出python命令窗口中 进入:python 退出函数:exit() 执行python文件 想要执行命令的话想要找到文件
Python 3.2后还引入了一个比较有意思的新类,叫Barrier,顾名思义,就是设置个障碍(设置数目n),等大家都到齐了(每个线程调用下wait,直到有n个线程调用),再一起出发。Python 3.3也在进程中引入了对应的此模块。此外,还有Timer可以用来处理各种超时情况,比如终结subprocess创建的进程。

服务器的监控通过安装一些常用的监控软件之外,有时也需要运行一些shell或Python脚本;shell下可以使用系统自带的ps/free/top/df等shell命令,Python可以调用subprocess等模块来运行shell命令,不过这么做就比较麻烦。这里有一个比较好用的第三方模块:psutil。 psutil是一个跨平台的库,用于在Python中检索有关运行进程和系统利...
