[Tex/LaTex] Latex-Python combination not running on a mac

Question

I am a beginner in Latex/Python and try to run the file below on my Mac (10.8.4 – latest MacTex). This is just a test file and it is not running. Python is running in the console and I have copied python.sty into the folder "library/texmf".

Can you tell me what the problem might be? Would be really helpful. I couldnt find any solution on the internet. Thanks in advance!!!

CODE

The %& -shell-escape first line is not sufficient to enable shell escape with TeX Live (MacTeX). This is confirmed by your log: you have

This is XeTeX, Version 3.1415926-2.5-0.9999.3 (TeX Live 2013)
 restricted \write18 enabled.

while it should be

This is XeTeX, Version 3.1415926-2.5-0.9999.3 (TeX Live 2013)
 \write18 enabled.

with shell escape enabled.

Here's how you can do with TeXworks.

Open the Preferences panel in TeXworks and go to the Typesetting tab

Click on the “+” button in the lower part

Now fill in the “Tool configuration” window as shown below

For adding a line in the “Arguments” section, click on the “+” button (three times, in this case).

Use the following first line in your document

% !TEX program = XeLaTeX+shell-escape

so that the typesetting tool will be the one just created.

The complete file will then be

% !TEX program = XeLaTeX+shell-escape
\documentclass{article}
\usepackage{python}
\begin{document}

Say hello Python:

\begin{python}%
print "hi"
\end{python}%

\end{document}

Here's the result after hitting the “compile” button:

You might add the --shell-escape argument to the standard XeLaTeX tool, but it's better not doing it, as shell escape should be enabled with caution only for “safe” file (your files or those coming from a trusted source).
