Python file read and write operations are performed interactively with the Linux shell variable commands

This example describes how Python file read and write operations interact with the Linux Shell variable command. Share to everyone for your reference. Specific as follows:

Python is easy to read and write to files, and the interaction variables with the Linux shell need to be converted to be used, which is more of a headache.

The code is as follows:

The code is as follows:

#coding =utf-8
#!/usr/bin/python
Import OS
Import time
#python执行linux命令
Os.system (': >./aa.py ')
#人机交互输入
S = Raw_input ("Input:")
os.environ[' s ']=str (s)
#把字符串S写入文件
Output = open ('./aa.py ', ' a ')
Output.write (S)
#关闭文件
Output.close ()
#python中的思考时间
Time.sleep (1)
#获取文件内容
f = open ('./aa.py ', ' R ')
Read = F.read ()
#变量间的转换
os.environ[' read ']=str (read)
Os.system (' $read ')
F.close ()
Var=os.popen (' Ifconfig '). Read ()
Print Var
