标签: pandas-datareader

我在虚拟环境中工作.我能够在没有任何错误的情况下导入和使用pandas,但是当我尝试时import pandas_datareader

import pandas as pd
import numpy as np
import matplotlib.pyplot as plt
import datetime as dt
from matplotlib import style
import pandas_datareader as web

它给出了以下错误 -

Traceback (most recent call last):
  File "stock.py", line 6, in <module>
    import pandas_datareader as web
  File "/home/xxxxx/django-apps/env/lib/python3.5/site-packages/pandas_datareader/__init__.py", line 2, in <module>
    from .data import (DataReader, Options, get_components_yahoo,

    from pandas_datareader.fred import FredReader

ImportError: cannot import name …

import pandas_datareader

end = "2022-12-15"
start = "2022-12-15"
stock_list = ["TATAELXSI.NS"]

data = pandas_datareader.get_data_yahoo(symbols=stock_list, start=start, end=end)

print(data)

当我运行此代码时，出现错误"TypeError: string indices must be integers"。

编辑：我已经更新了代码并将列表作为符号参数传递，但它仍然显示相同的错误

错误 ：

Traceback (most recent call last):

    data = pandas_datareader.get_data_yahoo(symbols=[TATAELXSI], start=start, end=end)

这可能听起来像一个noob问题,但我坚持使用它,因为Python不是我最好的语言之一.

我有一个html页面,里面有一个表格,我想在其中显示一个pandas数据帧.最好的方法是什么？使用pandasdataframe.to_html？

PY

from flask import Flask;
import pandas as pd;
from pandas import DataFrame, read_csv;

file = r'C:\Users\myuser\Desktop\Test.csv'
df = pd.read_csv(file)
df.to_html(header="true", table_id="table")

HTML

<div class="table_entrances" style="overflow-x: auto;">

  <table id="table">

    <thead></thead> 
    <tr></tr>

  </table>

</div>

我是Python 3x的新手,在mac上运行.

目前使用带有finance的python的sentdex教程,尝试运行以下脚本:

import datetime as dt
import matplotlib.pyplot as plt
from matplotlib import style
import pandas as pd
import pandas_datareader.data as web

style.use('ggplot')

start = dt.datetime(2000,1,1)
end = dt.datetime(2016,12,31)

df = web.DataReader('TSLA', 'yahoo', start, end)
print(df.head())

但是,这会返回以下错误消息:

Traceback (most recent call last):
  File "F:\Downloads\Python Work\try figuring thigns out\finance\try.py", line 1, in <module>
    import pandas_datareader.data as web

请注意:这个问题在下面成功回答了ptrj.我还在我的博客上写了一篇关于我对zipline的体验的博客文章,你可以在这里找到:https://financialzipline.wordpress.com

我的总部设在南非,我正在尝试将南非股票加载到一个数据框中,以便它可以提供带有股价信息的zipline.假设我正在寻找在JSE(约翰内斯堡证券交易所)上市的AdCorp控股有限公司:

Google财经为我提供了历史价格信息:

https://www.google.com/finance/historical?q=JSE%3AADR&ei=5G6OV4ibBIi8UcP-nfgB

雅虎财经没有关于该公司的信息.

https://finance.yahoo.com/quote/adcorp?ltr=1

在iPython Notebook中键入以下代码,可以获得Google财经信息的数据框:

start = datetime.datetime(2016,7,1)
end = datetime.datetime(2016,7,18)    
f = web.DataReader('JSE:ADR', 'google',start,end)

如果我显示f,我看到该信息实际上也与Google财经相关信息相对应:

这是Google财经完全关闭的价格,您可以在Google财经网站上看到2016-07-18的信息与我的数据框完全匹配.

但是,我不确定如何加载此数据框,以便zipline可以将其用作数据包.

如果查看给出的示例buyapple.py,您可以看到它只是从摄取的数据包中提取了apple share(APPL)的数据quantopian-quandl.这里的挑战是更换APPL,JSE:ADR以便它JSE:ADR每天订购10 份数据,而不是数据包,quantopian-quandl并将其绘制在图表上.

有谁知道如何做到这一点？网上几乎没有关于这个问题的例子......

这是buyapple.pyzipline示例文件夹中提供的代码:

from zipline.api import order, record, symbol


def initialize(context):
    pass


def handle_data(context, data):
    order(symbol('AAPL'), 10)
    record(AAPL=data.current(symbol('AAPL'), 'price'))


# Note: this function can be removed if running
# this algorithm on quantopian.com
def analyze(context=None, …

我已经安装了pandas-daatreader但是已经弃用了用于下载历史股票价格数据的Google和Yahoo API.

import pandas_datareader.data as web
start_date = '2018-01-01'
end_date = '2018-06-08'
panel_data = web.DataReader('SPY', 'yahoo', start_date, end_date)

ImmediateDeprecationError: 
Yahoo Daily has been immediately deprecated due to large breaks in the API without the
introduction of a stable replacement. Pull Requests to re-enable these data
connectors are welcome.

See https://github.com/pydata/pandas-datareader/issues

你能告诉我如何使用Python访问历史股票价格吗？事实上,我有兴趣在研究时尽可能地提价.

谢谢.

由于雅虎停止了他们的 API 支持，pandas datareader 现在失败了

import pandas_datareader.data as web
import datetime
start = datetime.datetime(2016, 1, 1)
end = datetime.datetime(2017, 5, 17)
web.DataReader('GOOGL', 'yahoo', start, end)

HTTPError: HTTP Error 401: Unauthorized

是否有任何非官方图书馆允许我们暂时解决这个问题？Quandl 上有什么吗？

我对使用熊猫数据阅读器的雅虎财务功能有疑问.我现在使用了几个月的股票代码清单,并按以下几行执行:

import pandas_datareader as pdr
import datetime

stocks = ["stock1","stock2",....]
start = datetime.datetime(2012,5,31)
end = datetime.datetime(2018,3,1)

f = pdr.DataReader(stocks, 'yahoo',start,end)

从昨天开始我收到错误"IndexError:list index out of range",只有当我试图获得多个股票时才出现.

最近几天有什么变化我必须考虑或者你有更好的解决方案吗？

I am trying to download historical data from Yahoo using Pandas datareader. This is the code that I normally use:

import pandas_datareader as pdr
df = pdr.get_data_yahoo('SPY')

However, I started receiving this error today: RemoteDataError: Unable to read URL: https://finance.yahoo.com/quote/SPY/history?period1=1467511200&period2=1625277599&interval=1d&frequency=1d&filter=history

Does anyone know how to solve it?

Thank you very much in advance!

尝试在 Python 311 上安装 lxml。遇到此错误。
