This is written for python 2 and you're using python 3.

I'm getting the following error:

C:\Python36\Lib\site-packages>python yahoo_finance.py aapl
File "yahoo_finance.py", line 12
print "Parsing %s"%(url)
^
SyntaxError: invalid syntax
Any tips?

@toxilate

This code is written for Python 2, dead giveaway is always print "Print function has no ( ) around what's after print". You are using Python 3. I hope that helps :-)

I am getting this error.
C:\Python36>python yahoo_finance.py APPL Fetching data for APPL Parsing https://finance.yahoo.com/quote/APPL?p=APPL Failed to parse json response Writing data to output file

Really great resource here. Thanks so much for making this. I am working on writing some code that generates fair price per share estimates and this will be integral to my WACC calculation.
ScrapeHero you are my hero!

I am trying to use Beautifulsoup. when I try to get a company details from Yahoo finance https://in.finance.yahoo.com/quote/HON?p=HON
name_box = soup.find("h2", attrs={"class": "Fz(m) Lh(1) Fw(b) Mt(0)"})
When I use the above code, I am geting "None" value
Please help me to figure out this.

I modified this to get currentPrice only, works. But for ETFs it does not work because there is no current price in json response.

For example:

https://query2.finance.yahoo.com/v10/finance/quoteSummary/EUNL.DE?formatted=true&lang=en-US&region=US&modules=summaryProfile%2CfinancialData%2CrecommendationTrend%2CupgradeDowngradeHistory%2Cearnings%2CdefaultKeyStatistics%2CcalendarEvents&corsDomain=finance.yahoo.com

Any idea to get this work for ETFs?

Any documentation that shows how to construct the query2.yahoo.finance url would be great, can't seem to find any and would love to scrape financial data.

TLRY (a cannabis stock) returned 'None' a well. If you're looking for historical data, you can download it for free in a .csv via NASDAQ. Great code though. Thanks!
