1.用python调用python脚本#!/usr/local/bin/python3.7importtimeimportoscount=0str=('pythonb.py')result1=os.system(str)

1.用python调用python脚本


#!/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:


#!/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

2.python调用shell方法os.system()


#!/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脚本如下:


#!/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

3.python调用shell方法os.popen()


#!/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')

运行结果:

[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。
