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，但是我一直收到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"功能的原因，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

您对这里的错误感到困惑.您会为 self.Ssock 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

您需要调用该类以产生一个实例:

You need to call the class to produce an instance:

straussbot = StraussBot()

您还在混合制表符和空格:

You are also mixing tabs and spaces:

请注意，第5到9行的缩进方式中有行，而其余的行中有点吗?这些是制表符，Python将其视为 8个空格.因此，您的 connectSock 方法在 __ init __ 的 inside 中缩进，而不被视为 StrausBot 上的方法.

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.

您必须坚持使用制表符或正义空格.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.
