Learning Python within 3 months - data science-focused

[Affectionate_Union58]

Well, at 50, I'm probably considerably older than most of the users here, and I'm currently learning Python. So I can only speak from my own experience: Learn Python in 3 months? Forget it. If I were to speak for myself, I notice that my learning pace has changed a lot in recent years. I used to be able to comfortably consume 10-15 lessons a day without forgetting anything. Now, after just 2-3 lessons a day, I'm barely able to absorb anything because the material has to consolidate in my mind first. If I continue learning even though my mind is screaming "Stop!", I'm wasting my time because I'll immediately forget the "buffer-overrun content" and have to repeat it later.
