Where do you want to return the data frame to?
Still in cmd or back to the OS or to a file or something else?
This is starting to sound like a language rather than a command shell.

Subject: [program-l] Python, any way to return values when using the cmd
module without using Globals?
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?
Thanks,
Al
