It might be worth while to look at web2py (http://web2py.com).

Here is a good tutorial: http://killer-web-development.com/

There are a few implementations of Python that generate code that can
run the browser. I'm currently using brython and its significantly
easier than struggling with JavaScript. It's not perfect by any means,
it has its own quirks and bugs but the developer is very responsive, the
product is getting better every month and I like to see the Python
community give it a bit more love

With respect, I don't think it's appropriate to direct a python beginner to 
PyPi.  Far better to direct him to the relevant resources (like Django) and 
focus him on the standard Python interpreter, hopefully version 3.

Besides that, there's the old expression. Premature optimization is the root of 
all evil.  Until Python is shown to be too slow for a given task, it's 
premature to think about speedups like Cython or even PyPi.

While Python can do that, using a web framework to process HTTP requests and 
generate HTML to display in the browser, I don't believe Python is the 
appropriate language for the task at hand.  Most web sites that do interactive 
formula calculations like you describe do it all in the browser using 
Javascript.  No need to have a web server do all that heavy lifting at all.  A 
simple html file would contain everything you need.

Even if you want to use Python to generate the web page and process events, 
you'll still have to master Javascript at some point to make the webpages more 
interactive.

There's a website called Python Tutor where you can write Python programs and 
it will show you the structures built in memory as it executes. It's  very 
useful for seeing how recursive functions work, or any function or class you 
call. It will also work for simple programs and it has an output console you 
can print to.  (Well, it's more like a print window, but it works.) Very good 
for beginners, I used it all the time when I was first learning, and I still 
use it for recursive functions, since PyCharm doesn't step through recursion in 
a clear way.

Consider PyPi. I never used it, but they say, it is faster than usual CPython

Really?  I'd strongly contrast the Python Package Index

While Python can do that, using a web framework to process HTTP requests
and generate HTML to display in the browser, I don't believe Python is
the appropriate language for the task at hand.  Most web sites that do
interactive formula calculations like you describe do it all in the
browser using Javascript.  No need to have a web server do all that

Even if you want to use Python to generate the web page and process

webpages more interactive.

Building a web site can be done with Flask, Django, aiohttp, or a
number of other frameworks. Generating graphs can be done with
matplotlib. Speed won't be a problem - a computer can do a LOT of
mathematical calculations in the time it takes to request something
over the internet.

Have fun exploring!
