TikZ: repeat a certain step between all other foreach-steps

Question

I have a (long) list, say \def\List{0, 4, 7, 11, 2, 3}.
I draw an animation with a foreach-loopfor that (this is a very small part of a very large tikzpicture):

But I would like to repeat the picture for "0" (that is the black filled one) after each number. Like as the list would look like 0, 4, 0, 7, 0, 11, 0, 2, 3, 0.

Is there maybe a trick to get that?

\documentclass[margin=5mm, tikz]{standalone} 
\usepackage{tikz}

\def\List{0, 4, 7, 11, 2, 3}

\begin{document}
\foreach \No in \List {%%
\begin{tikzpicture}[]
\pgfmathsetmacro\Fill{\No==0 ? "black" : "none"}
\node[draw, minimum size=10mm, name=ListEntry, fill=\Fill]{\No};
\node[anchor=west] at (ListEntry.east){Situation: \No};
\end{tikzpicture}
}%%
\end{document}

Answer 1

You can put a second tikzpicture inside the loop:

\documentclass[margin=5mm, tikz]{standalone} 
\usepackage{tikz}

\def\List{4, 7, 11, 2, 3}

\begin{document}
\foreach \No in \List {%%
\begin{tikzpicture}[]
\node[draw, minimum size=10mm, name=ListEntry, fill=black]{0};
\node[anchor=west] at (ListEntry.east){Situation: 0};
\end{tikzpicture}
\begin{tikzpicture}[]
\node[draw, minimum size=10mm, name=ListEntry]{\No};
\node[anchor=west] at (ListEntry.east){Situation: \No};
\end{tikzpicture}
}%%
\end{document}

Alternatively you can add a nested loop:

\documentclass[margin=5mm, tikz]{standalone} 
\usepackage{tikz}

\def\List{4, 7, 11, 2, 3}

\begin{document}
\foreach \No in \List {%%
\foreach \B[evaluate=\B as \k using {int(\No*\B)}] in {0,1}{%%
\begin{tikzpicture}[]
\pgfmathsetmacro\Fill{\B==0 ? "black" : "none"}
\node[draw, minimum size=10mm, name=ListEntry, fill=\Fill]{\k};
\node[anchor=west] at (ListEntry.east){Situation: \k};
\end{tikzpicture}
}}%%
\end{document}
