Unfortunately you seem to have picked the wrong snippets, which by the way
look made-up. The only error I see

if key in skipList:
    ...

should probably be
    
if cycle in skipList:
    ....

The "most basic" error would be a print statement producing

> DEBUG: begin main procedure

sitting in a second place where it doesn't belong and isn't expected.

Other than with a buggy C-extension that is not possible.
