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
['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。
