Hi all, I am wondering what the best way to do the following would be: throw an exception, or always return an object but set an error flag if something goes wrong? Here is an example:
class c: def __init__(self): self.error=False def func(self, val): if val!=10: self.error=True someObj=c() someObj.func(5) if someObj.error: #do stuff OR: class c: def __init__(self): self.error=False def func(self, val): if val!=10: throw ValueError #I know the syntax is wrong someObj=c() try: someObj.func(5) except: #do stuff Which is the "standard" way when dealing with objects? Throw exceptions or always return an object, even if said object has an error and may therefore not have data beyond an error code and message? If I go the exception route, can I somehow put a message into the exception, maybe adding it as an attribute of my custom exception class? I assume so... except e: print e.message or something like that. I know I have research to do about the specifics of all this, but before I go off and look it all up I am wondering if it is the best way to go as far as standards and best coding practices. This is still that api wrapper, so I am not the only one who may end up using this file and I want to make it into something that is useable and does what people expect.
