It is certainly B & C.  It is a common issue.  There is no way to avoid 
it unless you learn how to avoid it.  Other than that, PyChecker may 
help find this kind of error.  Over a year ago Guido said he wanted to 
include pychecker with python but it still hasn't happened, so you can 
download it from here: http://pychecker.sourceforge.net/
