我正在尝试运行以下代码,我正在使用Spyder。我还有另一个也使用pandas_datareader的文件,但我也从未在该文件上收到错误消息,该文件也在Spyder上运行。另外,另一个文件也使用yahoo,所以我也不认为这是问题所在。我的问题是:我的代码中是否有某些特殊内容导致该文件没有数据读取器模块?
import bs4 as bs
import datetime as dt
import os
import pandas_datareader.data as web
import pickle
import requests
def save_sp500_tickers():
resp=requests.get('https://en.wikipedia.org/wiki/List_of_S%26P_500_companies')
soup=bs.BeautifulSoup(resp.text, 'lxml')
table=soup.find('table',{'class':'wikitable sortable'})
tickers=[]
for row in table.findAll('tr')[1:]:
ticker=row.findAll('td')[0].text
tickers.append(ticker)
with open('sp500tickers.pickle','wb') as f:
pickle.dump(tickers, f)
print(tickers)
return tickers
#save_sp500_tickers()
def get_data_from_yahoo(reload_sp500=False):
if reload_sp500:
tickers=save_sp500_tickers()
else:
with open('sp500tickers.pickle','rb') as f:
tickers=pickle.load(f)
if not os.path.exists('stock_dfs'):
os.makedirs('stock_dfs')
start=dt.datetime(2016,1,1)
end=dt.datetime(2019,5,27)
for ticker in tickers:
print(ticker)
if not os.path.exists('stock_dfs/{}.csv'.format(ticker)):
df=web.Datareader(ticker, 'yahoo', start, end)
df.to_csv('stock_dfs/{}.csv'.format(ticker))
else:
print('Already have {}' .format(ticker))
get_data_from_yahoo()
答案 0 :(得分:0)
尝试一下:
from pandas_datareader import data, wb
然后使用:
data.DataReader('path')
