triestpa / cryptocurrency-analysis-python Goto Github PK

I tried with Github notebook, but encountered exception during the following step
altcoins = ['ETH','LTC','XRP','ETC','STR','DASH','SC','XMR','XEM'] altcoin_data = {} for altcoin in altcoins: coinpair = 'BTC_{}'.format(altcoin) crypto_price_df = get_crypto_data(coinpair) altcoin_data[altcoin] = crypto_price_df

but it works if I directly used in browser address bar

What went wrong?

Kindly, help me, I could not find the way out. Here is the full trace image of the error:

Please let me know the reason for this file not found and how to find or generate the file?

Hi, I have a question:

I've posted my Quandl API Key into this row:
quandl.ApiConfig.api_key = os.environ['API KEY']

File "C:***\Python\Github\Cryptocurrency Analysis\Cryptocurrency-Pricing-Analysis.py", line 74, in
quandl.ApiConfig.api_key = os.environ['API KEY']
File "C:\ProgramData\Miniconda3\lib\os.py", line 669, in getitem
raise KeyError(key) from None
KeyError: 'API Key'
[Finished in 1.9s]

I'm working via Mininconda in Sublime Text. Using Jupyter doesn't work either. Any idea?
