====== Python中遍历类的成员变量 ======
在Python中经常会遇到新的类，有时候需要遍历一下类的成员变量和函数，用dir只能看到成员的名字，而且也不能区分成员是变量还是函数。
====== Python类遍历实现代码 ======
下面的Python代码就实现了遍历类成员，并将成员变量打印出来。
types = [type(i) for i in [0, "0", [0], {0:1}, (0,)]]
content = ""
for k in dir(self.request):
content += "%s: %s\n" % (k, type(eval("self.request.%s" % k)))
if type(eval("self.request.%s" % k)) in types:
content += "%s\n" % str(eval("self.request.%s" % k))
content += "\n"
print content

Abstraction for an HTTP request.
Properties:
uri: the complete URI requested by the user
scheme: 'http' or 'https'
host: the host, including the port
path: the path up to the ';' or '?' in the URL
parameters: the part of the URL between the ';' and the '?', if any
query: the part of the URL after the '?'
You can access parsed query and POST values with the get() method; do not
parse the query string yourself.
