mcgrew, 20 days ago I just remembered a Python behavior I learned about in college that could have bitten me: >>> def addbork(borklist=[]): ... borklist.append('bork') ... return borklist ... >>> addbork() ['bork'] >>> addbork() ['bork', 'bork'] This happens because the default argument is instantiated when the function is defined rather than when it is called, so any changes to the object persist on subsequent calls. #python #programming
