I love Python for back-end web development, it's hard to shake it off of me, except if I were doing ASP .NET Core (I'm ok with C#). So I think in that area it's pretty solid, but I agree, I wish the GUI side of Python got more love, maybe a proper RAD environment like VB had, hate on VB all you want, but damn it was neat. I'm surprised Kivy doesn't have a RAD editor, if it does then I am way behind. For now I'll keep using Tkinter.
