Thanks for all you suggestions. The is a lot of good ressources. The official doc - Obviously very useful; Realpython - Seems to be good. I will try it; Udemy - Too much courses for beginners; Udacity - Seems to be good to see some examples for not for what I want now; O'reilly - A little bit expensive; Pluralsight - Seems to be good; Lynda - I like this http://www.lynda.com/search?q=code+clinic , to view the differences between all languages. I like the idea. Very nice; Pylint - Seems to be a good tool. I will use it; Stromberg - I don't like the course format;
For now, I think I will try Realpython.com and Pluralsight. I will use Pylint when I will be more confident. Thanks for your help. -- https://mail.python.org/mailman/listinfo/python-list
