I never see any of the cool guys mentioning web2py. Thinking of using it in an upcoming project. Wonder what is "wrong" with it? :-)
And if I may add mine - the arguments brought forth by Jacobian (Kaplan Moss, of Django fame) and Mitsushiko (Ronacher, of Flask fame) belong in the fiction department. Hundreds of web2py apps later, no one is confused by the additional 15 builtins, or by the concat-then-exec behavior. I am active on the web2py mailing list, and in two years and thousands of newbie questions, I don't remember a single one where this caused the fearful confusion that jacobian and matsushiko fear so much.
If you have any experience programming and want to learn Python for the purpose of developing web applications, the web2py book is a good resource.
