1.用python調(diào)用python腳本

#!/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')

另外一個python腳本b.py如下：

#!/usr/local/bin/python3.7
print('hello world')

運行結(jié)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調(diào)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腳本如下：

#!/bin/sh
echo "hello world"

運行結(jié)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調(diào)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')

運行結(jié)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() 這個方法會打開一個管道，返回結(jié)果是一個連接管道的文件對象，該文件對象的操作方法同open()，可以從該文件對象中讀取返回結(jié)果。如果執(zhí)行成功，不會返回狀態(tài)碼，如果執(zhí)行失敗，則會將錯誤信息輸出到stdout，并返回一個空字符串。這里官方也表示subprocess模塊已經(jīng)實現(xiàn)了更為強大的subprocess.Popen()方法。

總結(jié)
