I’ve read in parts of the web (and on the Martinelli’s Python Cookbok) that it’s better to do the Borg pattern over singletons, they say something alongs the lines of:
“who cares about identity, care about shared state”
Coming from the Java world, I just can’t understand that, why waste memory and cpu to address objects that share a state when you can have a single object in memory.
If you’re looking on how to implement singleton in a simple manner with Python, do the following my friend:
class MyClass: __INSTANCE__ = None def __init__(self): #do whatever you need on your constructor pass @staticmethod def getInstance(): if MyClass.__INSTANCE__ is None: MyClass.__INSTANCE__ = MyClass() return MyClass.__INSTANCE__ #Then use it. theOne = MyClass.getInstance()
Done deal, now start trolling on why this code sucks so we can fix it.
