Python file read and write operations interactively executed with Linux shell variable commands

This article illustrates how to interactively execute python file read and write operations with Linux shell variable commands. Share with you for your reference. The details are as follows:

Python is easy to read and write to files, and the Linux shell's interactive variables need to be converted to use, which is a headache.

The code is as follows:

#coding=utf-8

#!/usr/bin/python

import os

import time

#python perform linux The command 

os.system(':>./aa.py')

# Human-computer interactive input 

S = raw_input("input:")

os.environ['S']=str(S)

# Put the string S Written to the file 

output = open('./aa.py','a')

output.write(S)

# Close the file 

output.close()

#python Thinking time in 

time.sleep(1)

# Get file contents 

f = open('./aa.py','r')

read = f.read()

# Transformation between variables 

os.environ['read']=str(read)

os.system('$read')

f.close()

var=os.popen('ifconfig').read( )

print var
