Pandas_datareader金融数据程序包下载出现的各种后续问题
由于要分析Google的历史股票价格数据进行可视化，导入了Pandas_datareader程序包
pip install pandas_datareader
导入数据：
from pandas_datareader import data
goog=data.DataReader('GOOG',start='2004',end='2016',data_source='google')
print(goog.head())
报错，出现以下问题：
Traceback (most recent call last):
File "E:/python数据/goole-finance.py", line 2, in
goog=data.DataReader('GOOG',start='2004',end='2016',data_source='google')

raise ImmediateDeprecationError(DEP_ERROR_MSG.format('Google finance'))
pandas_datareader.exceptions.ImmediateDeprecationError:
Google finance 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.

查找原因，说是还要引用一个库fix-yahoo-finance，直接pip安装
pip install fix-yahoo-finance
cmd出现错误：
后来在pypi下载离线安装包，依然存在这个问题，直到无意看到这个：
意思就是说，这个包改名了，你要用yfinance这个名字。。。。。。（论英语的重要性==）
pip install yfinance
终于搞定！没有报错了
参考另外两位博客：
https://blog.csdn.net/Hellolijunshy/article/details/82527643
https://blog.csdn.net/qq_24974989/article/details/82875029
运行代码：
import pandas_datareader.data as web
import yfinance as yf
import datetime
yf.pdr_override()
start=datetime.datetime(2004,8,19)
end=datetime.datetime(2012,1,1)
apple=web.get_data_yahoo('GOOGL',start,end)
print(apple.head())
运行结果：
