start_directory = r'D:\testdir'
os.system("explorer.exe %s" % start_directory)

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

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)
