This article describes how to use Python to call the system Shell in Linux, including reading a row of files using Python and shell, for more information about how to mount a file system, you must directly call the Shell command to complete some simple operations. So how can we use
Python System Operations Common Library1. Psutil is a cross-platform library (http://code.google.com/p/psutil/)It is able to achieve the process and system utilization (memory, CPU, disk, network, etc.) of system running, which is mainly used for system monitoring, analysis

1, built-in function open(file_name,文件打开模式,通用换行符支持) , open file return file object.
2, when the open file to read, readline() the readlines() difference is whether to read all the content one time, and each line of information as a child in the list.For example:
Most of the system interfaces in Python are concentrated in two modules: SYS and OS. That's a little simplistic. There are also other table-to-module modules that fall into this area. They include:Glob Extensions for file namesSocket for network connection and interprocess communication (IPC)Threading,_threading,queue for running and synchronizing session concurrent threadsThe Time,timeit is used to obtain
The python script can be used to set the system time.
This article shares two methods for setting the system time using python scripts for your reference. The specific content is as follows:
