# [Tex/LaTex] Figure environment not working with included file (extra } or forgotten endgroup)

colorfloatsincludeprogramming

I've spent hours on this issue. I hope someone can help me. I'm running into some kind of interference when I try to use the figure environment (Likewise for table, might be related to floats). I finally narrowed the problem down to one line– where I include another file in the preamble that allows me to later include python code and have Latex color code it. The code I'm trying to compile is:

\documentclass[10pt]{article}
\include{pythonperfect}
\usepackage{graphicx}
\begin{document}
\begin{figure}
blah blah blah
\end{figure}
\end{document}


where "pythonperfect" is:

The error I get is:

! Too many }'s.
\color@endbox->\color@endgroup \egroup
l.10 \end{figure}
You've closed more groups than you opened.
Such booboos are generally harmless, so keep going.
! LaTeX Error: \begin{document} ended by \end{figure}.


In any case, I've used "pythonperfect" for a while, and never ran into an issue until today when I tried to include a figure. The problem is that I don't really understand most of what's happening in that file, I found it somewhere on the web (I don't remember where) and made a few changes to make it work for me. But I don't really understand it. So I can't figure out what's wrong.

I'd really appreciate any help. Thank you very much.

#### Best Answer

As Martin Scharrer mentioned in his comment, the example works. However, I think the problem starts in the moment you use the newly defined environment \lstnewenvironment.

There was a closing } missing and when you used

\begin{python}

\end{python}


the error message came up. Have a look at this file's very last line. I also un-commented the new environment definition.

And the example

\documentclass[10pt]{article}
\input{pythonperfect}%input better than include here
\usepackage{graphicx}
\begin{document}

\begin{python}
