本文实例讲述了python文件读写操作与linux shell变量命令交互执行的方法。分享给大家供大家参考。具体如下:

python对文件的读写还是挺方便的,与linux shell的交互变量需要转换一下才能用,这比较头疼。

代码如下:

代码如下:


#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

希望本文所述对大家的Python程序设计有所帮助。
