Unfortunately you forgot to attach your Python code.

If your code is short, say less than 100 lines, please just copy and 
paste it into the body of your email. 

If it is more than 100 lines but less than, say, 300, attach it as a .py 
file. If it is bigger than that, please don't send it to the mailing 
list without asking first. We are volunteers, and it is very unlikely 
that anyone is going to spend hours working through a ten thousand line 
file trying to debug it on your behalf.

Thank you,
