[Tutor] python investment scheme assistance

[Binish Huma Qadir]

Hi,

I'm doing a Investment implementation project where i need to use the
following data:
http://app.lms.unimelb.edu.au/bbcswebdav/courses/600151_2008_1/datasets/finance/asx_large.csv

I've been instructed to design an investment scheme in python.
The investment scheme i have chosen is based on investing in 3companies
with the highest dividend yield and lowest debt equity ratio.

The problem is that i dont know how to set up a python code that gives me
the top 3 companies with the above characterisics.

Your help would be much appreciated.
Thank you very much for your time.
Regards,
Binish
