I was just guessing from OPs post saying that they don't even have basic highschool math knowledge, from which I would assume that translating mathematical concepts into concepts in Python would probably create more difficulties than necessary, whereas in Alpha you can just dump an equation and then get an interpretation. Matplotlib in particular is kind of an expert interface for a library, at least when I last checked it out.
Desmos looks interesting.
I use Desmos all the time when teaching. It's accessible to students with no programming knowledge, and the killer feature is that I can just give students a link so they can interact with a demo I've made.
For example:
Quadratic through 3 points (drag the points around): https://www.desmos.com/calculator/tf1f80zgug
Pythagoras's Theorem (drag the sliders): https://www.desmos.com/calculator/dbjxbeuzk7
Why shearing preserves area (drag the slider): https://www.desmos.com/calculator/1vykaqf7je
I do use and recommend http://desmos.com, which is proprietary (but pretty limited and easily translated to Python). It doesn't lock features behind a paywall like Wolfram Alpha.
