簡單了解python調用其他腳本方法實例
1.用python調用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模塊已經實現了更為強大的subprocess.Popen()方法。
