How do online platforms like Codecademy, Coursera, and edX ensure that their free Python courses are accessible and effective for a diverse range of learners?

Any free python courses are said to be good if its simple enough.

The sad truth is that python despite being simple, is actually much more complex when you are supposed to be implementing more complex solutions. The syntax gets much harder.

But for beginners, python is supposed to be a general syntax script tool, not a hardcore programming language. If you want to learn it as a programming tool, there is no such course that goes into such depth.

BECAUSE it is not possible😂 and I have a 800 page book to prove that. Python as a scripting tool is already too good to be even existing.

You can build scalable solutions in it if you know it good enough and that kind of information is available through books only. Nobody is giving that for free, unless you are some really caring guy and have gone through such hardships to learn the stuff.

Online courses are good and you should study them just to get to know the language. Once you are done, research and get the right books. Luckily, there are very good number of books that teaches python really really really well.
