`exec`-based routine crashes app upon migration from 3.4.3 to python 3.5.2.

I've manually set breakpoints and traced this app crash back to this function: def loadLSobjsOfType(self, objType, listJ): if listJ != None: for objJ in listJ: _locals = locals() exec('obj = ' + objType + '(self)', None, _locals)

Re: Thoughts on python classes to represent an ebook reader

Thanks a lot. It is quite helpful to follow the thought process here. Another person gave the example of 'Calibre', but I've found it overwhelming and I couldn't find any UML diagram there (maybe not searched hard enough). Regards, Felix -- https://mail.python.org/mailman/listinfo/python-list

Thoughts on python classes to represent an ebook reader

Hi, I hope there are people here with strong OOP experience. Which classes would an object-oriented python programmer create for the design of a e-book reader for example? I am not really interested in the code, just the OOP classes that would come to one's mind for a task like this. It should

how to parse standard algebraic notation

Hi, I am trying to learn Python while solving exercises. I want to basically write a program that inputs a polynomial in standard algebraic notation and outputs its derivative. I know that I need to get the exponent somehow, but I am not sure how to accomplish this in python (3.3) Do you hav

DatBases and Pickle Module

without any kind of DBMS. I wonder how they did this? It also seems alot faster then when working with DBMS. Can I achieve the same in Python with say..the pickle module. For instance a dictionary or something else? Many thanks to you all Math -- http://mail.python.org/mailman/listinfo/python
