Actually think I have found the cause and its really small but on way its
called.
I was calling
python3 racemeeting.py data/*.xml
which gives the directory and file as the path
['data/20160528RAND0.xml']
But with arguments separated by a space I actually receive what i thought I
would get a path and extension such as
sayth@localhost pyXML]$ python3 racemeeting.py data/ *.xml
Namespace(extension='', path=['data/', '*.xml'])
Traceback (most recent call last):
File "racemeeting.py", line 35, in <module>
