Butwhat does this metaclass actually dofor this class? Well, when a new class is made using our metaclass, our metaclass'sinitializer methodwill be called. Our metaclass's initializer method will ensure that all subclasses of our base class (thePluginclass in our case) are added to theplugin...
When Does Python Create Cache Folders? The interpreter will only store the compiled bytecode of Python modules in the__pycache__folder when youimportthose modules or sometimes their parent package. It won’t create the cache folder when you run a regular Python script that doesn’t import any...
In this step-by-step tutorial, you'll get a clearer understanding of Python's object model and learn why pointers don't really exist in Python. You'll also cover ways to simulate pointers in Python without the memory-management nightmare.
By default, Python still uses timestamp-based invalidation and does not generate hash-based .pyc files at runtime. Hash-based .pyc files may be generated with py_compile or compileall. Hash-based .pyc files come in two variants: checked and unchecked. Python validates checked hash-based ....
In other words, instances of descriptors can now know the attribute name of the descriptor in the owner class: class IntField: def __get__(self, instance, owner): return instance.__dict__[self.name] def __set__(self, instance, value): if not isinstance(value, int): raise ValueError...

In this tutorial, you will learn about namespaces and their importance. You will also learn about different ways of importing an external module in Python and the reasons to choose one method over ano
