Use the Python language to compile and obtain basic Linux system information (1): Obtain the Linux version, kernel, current time, And pythonlinux

I have been applying for a blog for a while, but I haven't written any more .....

I did not think of anything to write. I recently learned the Python language and read the most basic things in the book. I found that I could not read them at all, in addition, I thought I understood it all today. I forgot it when I reviewed this part of content in two days, so I thought that I could learn and write some small programs so that I could better remember the syntax.

I. Development Environment and test environment

Python2.7.10, pycharm, vmvm, CentOS6.3

Ii. Code Implementation

Code structure:

Commands. py-> OS _info_in.py-> OS _info.py |

Linux_status.py | --> linux_status_main.py

Implementation:

Commands. py:

Run the Linux Command in Python code to obtain the printed result set and return the result results.

 

1 # coding=UTF-82 import os3 class commands:4     def __init__(self,comm):5         self.commend=comm6     def excute_command(self):7         result = os.popen(self.commend)8         results = result.readlines()9         return results

 

OS _info_in.py:

Import the commands. py module you just compiled to obtain the Linux OS version number, kernel version number, and current time.

Record:

Remove spaces before and after eachLine. strip ()

Findall ('description: \ t # (. *) ', afind) searches for the content that matches the Regular Expression

1 #! /Usr/bin/env python 2 # coding = UTF-8 3 import commands 4 import re 5 class OS _info_in: 6 def OS _version (self): # Get linux OS Version 7 L_command = commands. commands ('lsb _ release-a') 8 comm = L_command.excute_command () 9 allLine = [] 10 OS _ver = ''11 for eachLine in comm: 12 allLine. append (eachLine. strip () 13 for afind in allLine: 14 if re. findall ('description: \ t #(. *) ', afind): 15 OS _ver = re. findall ('description: \ t #(. *) ', afind) 16 return OS _ver [0] 17 def OS _kernel (self): # Get linux kernel version 18 L_command = commands. commands ('uname-R') 19 comm = L_command.excute_command () 20 allLine = [] 21 for eachLine in comm: 22 allLine. append (eachLine. strip () 23 return allLine [0] 24 def OS _date (self): # obtain the system time 25 L_command = commands. commands ('date') 26 comm = L_command.excute_command () 27 allLine = [] 28 for eachLine in comm: 29 allLine. append (eachLine. strip () 30 return allLine [0]

Linux_status.py:

Save the obtained linux status information

1 #! /Usr/bin/env python2 # coding = UTF-83 # Save linux status information 4 # OS Version: OS _version5 # kernel version: OS _kernal6 # system current time: OS _date7 class linux_status: 8 pass

 

OS _info.py:

The linux status information obtained through OS _info_in.py is saved to the linux_status class for storing the status information and returned

 1 # coding=UTF-8 2 import linux_status 3 import os_info_in 4 class os_info: 5     def __init__(self): 6         self.linux_stat=linux_status.linux_status() 7         self.os_infos_in= os_info_in.os_info_in() 8     def os_info(self): 9         self.linux_stat.os_version = self.os_infos_in.os_version()10         self.linux_stat.os_kernal = self.os_infos_in.os_kernel()11         self.linux_stat.os_date = self.os_infos_in.os_date()12         return self.linux_stat

 

Linux_status_main.py:

Test the main function (print the obtained information)

1 #! /Usr/bin/env python 2 # coding = UTF-8 3 import linux_status 4 import OS _info 5 6 # linux version, kernel, time 7 linux = linux_status.linux_status () 8 OS = OS _info. OS _info () 9 linux = OS. OS _info () 10 print 'System: ', linux. OS _version11 print 'kernel: ', linux. OS _kernal12 print 'time: ', linux. OS _date

 

Iii. Result Display

 

 

 

 

Since I was just familiar with the Python language, I feel that the structure of the applet is redundant and it is easy to understand it by dividing it into one piece. I don't feel that I need to store the results in one class, you can store it in a dictionary (not very familiar with the dictionary at the time). You can save it in a dictionary to obtain the file system status in the future. Write it here and write it slowly...

For the first time, I hope you can give more comments ~~~~~ Xi ~~~~
