Когда я изучаю, как получить данные из Википедии S & P 500, получил какую-то ошибку, моя цель - получить данные из Википедии и провести анализ с помощью Python, все они следуют обучающему видео, я очень начинающий пользователь Pythonили код,
вот мой код
import bs4 as bs
import datetime as dt
import os
import pandas as pd
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
#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(2000,1,1)
end = dt.datetime(2016,12,31)
for ticker in tickers:
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()
Я исправил все ошибки форматирования и отступа, но терминал сказал
