First of all, many thanks to everyone who is helping me along my path by ansering countless questions on this list. I am resolving issues, learning a bit more every day. Of course, the more I learn, the more I realize I don't know. My latest issue yet again has to do with the cmd module. The problem is that I was hoping to use it to implement for example, a method called do_new (). Do_new would prompt for a ticker symbol, read the data into a Pandas DataFrame, and then return the DataFrame. However, cmd's methods apparently don't return values other than success or failure codes. I can make this work if I declare my DataFrame as a global variable but of course, I assume there must be a better way?
