Aiming for create my personal stock screener but not sure where to start with.

[pythonocc]

So basically your advise would be just try to learn most of the basic on python available under the first and second link then only further research on what kind of language I need to use? I planned to practice/learn it at least half hour per day, what do you think?

Thank you for the reply btw !

Also I just wondering whether to take Python 3 or the older version Python. Seems both of it feel different according to what I had Googled.
