Python类找不到属性 [英] Python class can't find attribute

问题描述

基本上，我想运行connect函数，但我不断收到CMD错误消息类StraussBot没有属性 connectSock，但显然可以看到。我尝试在此处进行搜索，但找不到该问题的任何解决方案。因此，如果您能帮助我找到为什么找不到'connectSock'函数的话，将不胜感激。

Basically, I want to run the connect function but I keep getting the CMD error message 'class StraussBot has no attribute 'connectSock' but I can obviously see it does. I've tried searching on here and I can't find any resolutions to this issue. SO it will be greatly appreciated if you could help me find why this isn't finding the 'connectSock' function.

代码：

import socket
    from config import HOST, PORT, CHANNEL

# User Info
USER = "straussbot" # The bots username
PASS = "oauth:sj175lp884ji5c9las089sm9vvaklf" # The auth code

class StraussBot:
    def __init__(self):
        self.Ssock = socket.socket()

    def connectSock(self):
        self.Ssock.connect((HOST, PORT))
        self.Ssock.send(str("Pass " + PASS + "\r\n").encode('UTF-8'))
        self.Ssock.send(str("NICK " + USER + "\r\n").encode('UTF-8'))
        self.Ssock.send(str("JOIN " + CHANNEL + "\r\n").encode('UTF-8'))

if __name__ == "__main__":
    print "Starting the bot..."
    while True:
        straussbot = StraussBot
        try:
            straussbot.connectSock()
        except Exception as e:
            print e

推荐答案

在这里被错误弄糊涂了。您会为 self.sock 获得 AttributeError ，因为您没有实例。

You are getting confused by the error here. You get an AttributeError for self.Ssock because you do not have an instance.

您仅在此处创建了对该类的引用：

You only created a reference to the class here:

straussbot = StraussBot

您需要调用该类以生成实例：

You need to call the class to produce an instance:

straussbot = StraussBot()

您还在混用制表符和空格：

You are also mixing tabs and spaces:

请注意第5至9行的缩进中有 lines ，但其余的都有点？这些是制表符，Python将其视为 8个空格。因此，您的 connectSock 方法在 inside 中缩进为 __ init __ ，而不被视为 StrausBot 。

Note how lines 5 through 9 have lines in the indentation, but the rest have dots? Those are tabs, and Python sees those as 8 spaces. So your connectSock method is indented inside of __init__ and not seen as a method on StrausBot.

您必须坚持使用 just tabs 或只是空格。 Python的样式指南强烈建议您仅使用空格。

You'll have to stick to either just tabs or just spaces. Python's styleguide strongly recommends you use spaces only.
