ironpython exception line number
Troels Thomsen
Hello ,
When an exeption occurs in a IronPython executet script, and I print the
sys.exc , i get something ugly like the example below.
How can I get the fileName and line number?
Thx in advance

You should get these results:

Which is very similar to the result you get from CPython although we seem to disagree about what we expect next.

If you're hosting IronPython and catching this from a .NET language then you'll be catching the .NET exception. In that case you can access the original Python exception from ex.Data["PythonExceptionInfo"]. Alternately you could catch PythonSyntaxErrorException and access its properties (Line, Column, FileName, LineText, Severity, and ErrorCode).
