对于将 pandas-datareader 与雅虎一起使用,当我在同一日期开始和结束时,当我在该日期询问时没有返回任何信息。如果我在一天后询问,它会起作用。但我想今天收盘。
import sys
from sqlalchemy import *
import os
import datetime
import pandas_datareader.data as web
end = datetime.datetime(2015, 10, 15)
start = datetime.datetime(2015, 10, 15)
path = 'c:\\python34\\myprojects\\msis\\'
try:
os.mkdir(path)
except:
pass
fname = path + 'test.txt'
fhand = open(fname, 'w')
engine = create_engine('mysql+mysqlconnector://root:@localhost /stockinfo')
connection = engine.connect()
result1 = engine.execute("select symbol from equities where daily = 'Y'")
for sqlrow in result1:
try:
info = web.DataReader(sqlrow[0], 'yahoo', start, end)
print (info)
close = info['Close'].ix['2015-10-14']
print ("=========================" + str(round(close,4)))
answer = "Closing price for " + sqlrow[0] + " is " + str(round(close,4)) + "\n"
except:
answer = "No success for " + sqlrow[0] + "\n"
fhand.write(answer)
# result2 = engine.execute("update holdings set lasrprice = " + round(close,4) + " where symbol = '" + sqlrow[0] + "'")
# result2.close()
result1.close()
fhand.close()
该代码采用第二条“例外”路线。
我做错了什么/发生了什么?
