New submission from Joshua De La Rosa <>:

Taking my first coding class, so I don't know much about coding or python in 
general, but I  ran into a problem when using the Debugger function for a 
homework assignment that neither I nor my professor could make sense of. My 
program executes successfully without running the Debugger or, in the case that 
I am running the Debugger, it only raises an error when I "Step" through the 
imported module that I implemented in another program, rather than just hitting 
"Go". The error it reports is:
AttributeError: '_ModuleLock' object has no attribute 'name'

Not sure which file to submit, since the I created my own module that is used 
in the program that raises the error when I step through it with the Debugger 
mode on.
