一、python/Django 寫文件
file_object = open('/opt/ result.txt','w')
file_object.write(gg)
file_object.close()
打開/opt目錄下的result.txt文件,並將字符串gg寫入result.txt文件
二、python/Django 讀文件
file_object = open('/opt/ test.py')
try:
gg = file_object.read()
finally:
file_object.close()
打開/opt目錄下的test.py文件,將文件內容賦值給gg,作爲一個長字符串
三、python/Django 程序中等待
import time
time.sleep(5)
四、python/Django 調用shell命令
import os, sys
cmdd = "python /opt/test.py"
os.system(cmdd)
或者
import os, sys
cmdd = "python /opt/test.py "
gg = os.popen(cmdd).read()
或者
import subprocess
process = subprocess.Popen(['service', 'httpd', 'restart'])
或者
import subprocess
r = subprocess.call("service httpd restart 1>$HOME/out 2>$HOME/error",Shell=True)
