1.用python调用python脚本
我要评论#!/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。
