使用熊猫从URL文件下载/加载xls

Question

I am trying to load the Excel file from the following URL into a dataframe using Python 3.5 and Pandas:

link = "https://hub.coursera-notebooks.org/user/ejquqxfjajkufidbixxvkx/notebooks/Energy%20Indicators.xls"

First I tried to download the file manually using urllib.request in order to read it right after:

import urllib.request
urllib.request.urlretrieve (link, "Energy Indicators.xls")

I got the file "Energy Indicators.xls", yes, but it is not a valid xls file. It seems more like a html file with the extension changed to xls.

Then I tried to load the file directly using read_csv:

energy = pd.read_csv(link, skiprows = 16, header = 0, skipfooter = 38)

But I got a traceback error: "pandas.io.common.CParserError: Error tokenizing data. C error: Expected 1 fields in line 12, saw 2". If I tried to read it without the arguments skiprows, header, etc. I got another error: "ValueError: Expected 1 fields in line 41, saw 3".

Any idea? BTW, I am using Mac OS Sierra and PyCharm Community Edition 2016.3

对于此特定的Coursera练习（不是一般情况），您不能在read_excel函数中使用整个URL，而只能使用“ Energy Indicators.xls”

energy = pd.read_excel('Energy Indicators.xls',...)
