python在这里抱怨什么？
我正在尝试运行 Adobe 的示例 python 策略服务器脚本，链接到此处： http ://www.adobe.com/devnet/flashplayer/articles/socket_policy_files.html
我收到以下错误：
# python flashpolicyd.py --file=policy.xml
File "flashpolicyd.py", line 40
with file(path, 'rb') as f:
^
SyntaxError: invalid syntax
在上下文中：
class policy_server(object):
def __init__(self, port, path):
self.port = port
self.path = path
self.policy = self.read_policy(path)
self.log('Listening on port %d\n' % port)
try:
self.sock = socket.socket(socket.AF_INET6, socket.SOCK_STREAM)
except AttributeError:
# AttributeError catches Python built without IPv6
self.sock = socket.socket(socket.AF_INET, socket.SOCK_STREAM)
except socket.error:
# socket.error catches OS with IPv6 disabled
self.sock = socket.socket(socket.AF_INET, socket.SOCK_STREAM)
self.sock.setsockopt(socket.SOL_SOCKET, socket.SO_REUSEADDR, 1)
self.sock.bind(('', port))
self.sock.listen(5)
def read_policy(self, path):
with file(path, 'rb') as f:
我对Python一无所知，所以这可能是非常简单和明显的事情。

I know nothing about python, so this may be something very simple and obvious.
