python调用其他脚本，,1.用python调

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：

[[email protected] while]$ python a.py hello world0this 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()

#!/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‘)

shell脚本如下：

#!/bin/shecho "hello world"

运行结果：

[[email protected] 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()

#!/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：

[[email protected] while]$ python a.py <os._wrap_close object at 0x7f7f89377940>[‘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。
