export the API key as an environmental variable. I recommend just adding it to your bashrc so it is always available.

#Should look somthing like "export ALPHA_VANTAGE_KEY=AHKDSFJHUDFDJD"
source ~/.bashrc

'''

'''
dnd.downloadNTopMarketCapCompanies(500, output_dir='stock_data')

output dir as a csv
