python实现得到当前登录用户信息的方法

def get_current_user():
  try:
    # pwd is unix only
    import pwd 
    return pwd.getpwuid(os.getuid())[0]
  except ImportError, e:  
    import getpass

    gid= pwd.getpwnam(user)[3]
    groups = grp.getgrgid(gid)[0]
  except KeyError, e:
    print( 'Failed to find primary group from user %s' ,user)
    return group
