Those data structures are, however, by definition local to your Python process. When several copies of your application run across a large platform, using a in-memory data structure disallows sharing the cached content. This can be a problem for large-scale and distributed applications. 但是,根据...

When del x is encountered, Python deletes the name x from current scope and decrements by 1 the reference count of the object x referenced. __del__() is called only when the object's reference count reaches zero. In the second output snippet, __del__() was not called because the ...
