1.用python調用python腳本python
#!/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')
另一個python腳本b.py以下:shell
#!/usr/local/bin/python3.7 print('hello world')
運行結果:ide
[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()學習

''' #!/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腳本以下:this
#!/bin/sh echo "hello world"
運行結果:code
[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()視頻

''' #!/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:對象
[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,返回結果是一個鏈接管道的文件對象,該文件對象的操做方法同open(),能夠從該文件對象中讀取返回結果。若是執行成功,不會返回狀態碼,若是執行失敗,則會將錯誤信息輸出到stdout,並返回一個空字符串。這裏官方也表示subprocess模塊已經實現了更爲強大的subprocess.Popen()方法。教程
