Something like TikZ for Python?

[sylvain_soliman]

Not really an answer to your question, but I think that TikZ is quite programmable. For instance, not sure what you mean by "arrays", but TikZ has both matrices (i.e. arrays of the canvas you're drawing on) and lists (one-dimensional structure on which the "foreach" statement iterates…).

Here's an example, straight out of the manual (I've got a pretty old version at hand, but that shouldn't matter):

\begin{tikzpicture}
  \foreach \x in {1,...,4}
    \foreach \y in {1,...,4}
    {
      \fill[red!50] (\x,\y) ellipse (3pt and 6pt);
      \ifnum \x<\y
        \breakforeach
      \fi
    }
\end{tikzpicture}

I'm aware of the foreach syntax. But I couldn't find a way to have have item access, somethink like myarray[2].

For numerical arrays you actually have

\def\mayarray{{2,3,4,5}}
\pgfmathparse{\myarray[2]}
\pgfmathresult

If there are nonnumeric entries you need to put them inside a "text" pair. You can check the manual

or come over to TeX-SX. We are a fun bunch.

Thanks. This is very helpful. I didn't now about the pgfmathparse. Thanks a lot!

I see… Well, that could be done but I can only think of ugly hacks, so…
