3.10 Python Binding<br />
Installing the <strong>TET</strong> edition for Python. The Python extension mechanism works by<br />
loading shared libraries at runtime. For the <strong>TET</strong> binding to work, the Python interpreter<br />
must have access to the <strong>TET</strong> Python wrapper which will be searched in the directories<br />
listed in the PYTHONPATH environment variable. The name of Python wrapper depends<br />
on the platform:<br />
> Unix and OS X: tetlib_py.so<br />
> Windows: tetlib_py.pyd<br />
Error Handling in Python. The Python binding translates <strong>TET</strong> exceptions to native<br />
Python exceptions. The Python exceptions can be dealt with by the usual try/catch<br />
technique:<br />
try:<br />
...some <strong>TET</strong> instructions...<br />
except <strong>TET</strong>Exception:<br />
print("<strong>TET</strong> exception occurred:\n[%d] %s: %s" %<br />
((tet.get_errnum()), tet.get_apiname(), tet.get_errmsg()))<br />
