Writing a simple CAS in Python

In my downtime, I'm writing a CAS in Python. It has to be from scratch, because I want it to fit on my calculator, and all of the solutions out there import a lot of data. Currently, there are two separate programs, one which can do full polynomial arithmetic, but you have to type in the polynomial in program form, as a list of coefficients starting from x^0. I'm working on merging it with the CAS interface, which will evaluate expressions recursively. For example: (sin x)^2 is sin inputted into the function f(y) = y^2. Though I don't have time to make this logic perfect, it will be interesting to learn how to program a u-substitution for arbitrary input.

What is the best parser abstraction?

Functional or object-oriented; don't really care which. Must be able to give detailed non-obstuse error messages.

Inline code can be embedded in several different ways:
  • \inline{ ... }
    or
    \lstinline{ ... }
    commands
  • \begin{inline} ... \end{inline}
    environment
  • \< ... \>
    or
    ` ... `
    special blocks

Block-level code can also be embedded in several ways:
  • \code{ ... }
    ,
    \codeblock{ ... }
    commands
  • \begin{code} ... \end{code}
    ,
    \begin{codeblock} ... \begin{codeblock}
    or
    \begin{lstlisting} ... \end{lstlisting}
    environments
  • ``` ... ```
    special block

Syntax highlighting can be added by specifying a programming language like
\begin[language=java]{code} ... \end{code}
or like
```java ... ```
.
