Pandas FinViz-库存刮送错误--未找到AMZN'；非类型'；对象没有属性'；查找下一个'；

我是新来的美女套餐。 我正在玩一个从某个网站上得到的代码，我被上面的错误卡住了。请帮忙

import pandas as pd
import re
from bs4 import BeautifulSoup as bs
import requests

def get_fundamental_data(df):
    for symbol in df.index:
        try:      
            url = ("http://finviz.com/quote.ashx?t=" + symbol.lower())
            soup = bs(requests.get(url).content) 
            for m in df.columns:                
                df.loc[symbol,m] = fundamental_metric(soup,m)                
        except Exception as e:
            print (symbol, 'not found')
            print(e)
    return df


def fundamental_metric(soup, metric):
    return soup.find(text=metric).find_next(class_='snapshot-td2').text

# Define A List Of Stocks And The Fundamental Metrics

stock_list = ['AMZN', 'GOOG', 'PG', 'KO', 'IBM', 'DG', 'XOM',
              'KO', 'PEP', 'MT', 'NL', 'ALDW', 'DCM', 'GSB', 'LPL']
metric = ['P/B',
          'P/E',
          'Forward P/E'
          ]

df = pd.DataFrame(index=stock_list, columns=metric)
df = get_fundamental_data(df)
df.head()

我运行了您的代码，当您

在for循环中打印（soup）

时，您会得到以下结果：

403-禁止：访问被拒绝。
服务器错误
403-禁止：访问被拒绝。
您没有使用您提供的凭据查看此目录或页面的权限。

我能够基于此线程修复自己的代码

修复后的我的代码：

@穆拉里

你的代码非常好，我有一个问题：如果我能从excel表格中导入符号，对我来说会更好。对于你的函数和下面的代码，我没有数据。在test.xlsx中，我只有一列带有符号：

            for m in df.columns:                
                df.loc[symbol,m] = fundamental_metric(soup,m)                
        except Exception as e:

错误在哪里？AMZN not found“NoneType”对象没有“find_next”属性。对于上个月代码运行的每个股票，都会收到相同的错误。这是ref网站：我有FinViz网站证书。但是我如何在代码中输入它呢？谢谢您的帮助。请尝试在此处添加用户名和密码：

requests.get（url，auth=（'user\u name'，'password'））

我尝试在函数之前声明我的用户和密码。但是没有运气。或者，您能给我更多关于我可以在哪里添加这些凭据的详细信息吗？请阅读以下内容：
