Question

我试图运行此代码：

import pandas as pd
df = pd.read_csv(r"C:\Users\Chaitanya\Desktop\Finsearch\AAPL.csv")
df = df.sort_values(by="Date")
df = df.dropna()
# calculate returns
df = df.assign(close_day_before=df.Close.shift(1))
df['returns'] = ((df.Close - df.close_day_before)/df.close_day_before)

# get options data from yahoo finance // in this case, exercise data is july 24th
r = pd.read_html('http://finance.yahoo.com/quote/AAPL/options?date=1655424000&p=AAPL')[0]

显示错误：

urllib.error.HTTPError: HTTP Error 404: Not Found``

Answer 1

您发布的堆栈跟踪似乎表明错误来自您未在问题中发布的代码：

Traceback (most recent call last): 
File "c:\Users\Chaitanya\Desktop\Finsearch\finserach.py", 
line 10, in **r = pd.read_html('http://finance.yahoo.com/quote/AAPL/options?date=1655424000&p=AAPL')**[0] File

特别是 r = pd_read_html('...) 部分。

urllib.error.HTTPError: HTTP Error 404: Not Found using pandas 即使 url 存在
