1.用python调用python脚本

#!/usr/local/bin/python3.7import timeimport os count = 0str = ('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:

#!/usr/local/bin/python3.7print('hello world')

运行结果:

[python@master2 while]$ python a.py hello worldthis count is: 1this count is: 2this count is: 3this count is: 4this count is: 5this count is: 6this count is: 7this count is: 8Good Bye

2.python调用shell方法os.system()

shell脚本如下:

#!/bin/shecho "hello world"

运行结果:

[python@master2 while]$ python a.py hello worldthis count is: 1this count is: 2this count is: 3this count is: 4this count is: 5this count is: 6this count is: 7this count is: 8Good Bye

3.python调用shell方法os.popen()

'''遇到问题没人解答?小编创建了一个Python学习交流QQ群:579817333 寻找有志同道合的小伙伴,互帮互助,群里还有不错的视频学习教程和PDF电子书!'''#!/usr/local/bin/python3.7import timeimport os count = 0n = 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')

运行结果:

[python@master2 while]$ python a.py ['hello world\n']this count is: 1this count is: 2this count is: 3this count is: 4this count is: 5this count is: 6this count is: 7this count is: 8Good 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。
