python类中出现NameError的问题

Question

报的错如下： class UserInfo(bidderID, name, addr, port): NameError: name 'bidderID' is not defined 代码如下： class UserInfo(bidderID, name, addr, port): bidderID = 0 #用户ID name = '' #用户名 addr = '' #IP地址 port = 0 #端口号 rname = '' #所在竞拍室名称 bidprice = 0 #出价 #UserInfo next = null def _init_(self, bidderID, name, addr, port): self.bidderID = bidderID self.name = name self.addr = addr self.port = port #打印用户关键信息,并返回包含用户信息的字符串 def printUserInfo(self): str = "\t用户ID: " + bidderID + "\t用户名: " + name + "\t出价: " + bidprice + "\n" return str U=UserInfo(1,"Alice","10.10.10.0",1) U.printUserInfo() 求问怎么回事？怎么解决？

Answer 1

class(object):
pass
类定义错误了，类名后面是继承，你却写成了初始化里面去了！低级错误
