A remark: that is unusual. Normally this would be a "logical" test: is 
yesterday a workholiday or not, returning True or False accordingly.  
Returning None will "test" as false, but it is not a normal value for 
false situations.

What does your function return when neither situation applies?

This is a text only list, and the list software discards most, if not 
all, attachments. Your sample file is not present in the email I 
received.

Please paste the contents of gwd.py directly into your email (which 
itself should be a _reply_ to this email or your original email). Then 
we can see your code.
