#!/usr/local/bin/python3.7

import time

import os

count= 0

str = ("python b.py")

result1= os.system(str)

print(result1)

while True:

count= count+ 1

if count== 8:

print("this count is:",count)

break

else:

time.sleep(1)

print("this count is:",count)

print("Good Bye")

另外一个python脚本b.py如下:

1

2

#!/usr/local/bin/python3.7

print("hello world")

运行结果:

[python@master2 while]$ python a.py

hello world

this count is: 1

this count is: 2

this count is: 3

this count is: 4

this count is: 5

this count is: 6

this count is: 7

this count is: 8

Good Bye

import os

count= 0

n= os.system("sh b.sh")

while True:

count= count+ 1

if count== 8:

print("this count is:",count)

break

else:

time.sleep(1)

print("this count is:",count)

print("Good Bye")

shell脚本如下:

1

2

#!/bin/sh

echo"hello world"

运行结果:

[python@master2 while]$ python a.py

hello world

this count is: 1

this count is: 2

this count is: 3

this count is: 4

this count is: 5

this count is: 6

this count is: 7

this count is: 8

Good Bye

if count== 8:

print("this count is:",count)

break

else:

time.sleep(1)

print("this count is:",count)

print("Good Bye")

运行结果:

[python@master2 while]$ python a.py

["hello world "]

this count is: 1

this count is: 2

this count is: 3

this count is: 4

this count is: 5

this count is: 6

this count is: 7

this count is: 8

Good Bye

os.system.popen() 这个方法会打开一个管道,返回结果是一个连接管道的文件对象,该文件对象的操作方法同open(),可以从该文件对象中读取返回结果。如果执行成功,不会返回状态码,如果执行失败,则会将错误信息输出到stdout,并返回一个空字符串。这里官方也表示subprocess模块已经实现了更为强大的subprocess.Popen()方法。
