I’m using Python 3.12 on Windows 10 Pro. I’m still somewhat new to Python. But I’ve been practicing writing different programs which do different things.

Currently, I’m reading Tutorial, Class Definition Syntax to learn some basic grammar about Python, especially the part of how Python creates and resolves the binding between name and object. Please look at the following code: def C(): breakpoint() # 1 class C: breakpoint() # 2 C C() According to the tutorial: When a class definition is entered, a new namespace is created … … When a class definition is left normally, a class object is created. This is basically a wrapper around the contents of the namespace created by the class definition. The original local scope ..read more
