1.用python调用python脚本python
#!/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')
另一个python脚本b.py以下:shell
#!/usr/local/bin/python3.7 print('hello world')
运行结果:ide
[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
2.python调用shell方法os.system()学习

''' #!/usr/local/bin/python3.7 import time 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脚本以下:this
#!/bin/sh echo "hello world"
运行结果:code
[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
3.python调用shell方法os.popen()视频

运行结果:对象
[python@master2 while]$ python a.py <os._wrap_close object at 0x7f7f89377940> ['hello world\n'] 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,返回结果是一个链接管道的文件对象,该文件对象的操做方法同open(),能够从该文件对象中读取返回结果。若是执行成功,不会返回状态码,若是执行失败,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。教程
