Is there a way to query a certain piece of information (ex. End of the Day Stock price) and/or all information related to the financial situation of all companies that exist in the database in Quandl via Python (instead of querying for a few companies at a time)?
If you know the name of all the companies, make a loop. I give you a hint:
for(companies in CompanyList):
data = Quandl.get(companies)
#then do whatever you want to do with the data!
If I am understanding right your question!
