python打开文件或目录的方法

一、利用explorer.exe
import  os
# 利用explorer.exe执行
start_directory  =  r 'D:\testdir'
os.system( "explorer.exe %s"  %  start_directory)

二、用os.startfile
import  os
# opens explorer at C:\ drive,just work for windows
start_directory  =  r 'D:\testdir'
os.startfile(start_directory)

三、利用subprocess
import  os
import  subprocess
# 利用subprocess

def  startfile(filename):
  try :
    os.startfile(filename)
  except :
    subprocess.Popen([ 'xdg-open' , filename])

start_directory  =  r 'D:\testdir'
startfile(start_directory)
