Aside: See callables in Python for more on the idea of a function being a class.A class's classEvery object in Python has a class.Even classes have a class. A class's class is its metaclass and that's what type is.That's interesting. But what's the purpose of a class having a...
Here's a fun project attempting to explain what exactly is happening under the hood for some counter-intuitive snippets and lesser-known features in Python.While some of the examples you see below may not be WTFs in the truest sense, but they'll reveal some of the interesting parts of ...
Python 2.7 is planned to be the last of the 2.x releases, so we worked on making it a good release for the long term. To help with porting to Python 3, several new features from the Python 3.x series have been included in 2.7....
class SomeClass(str): def __eq__(self, other): return ( type(self) is SomeClass and type(other) is SomeClass and super().__eq__(other) ) # 当我们自定义 __eq__ 方法时, Python 不会再自动继承 __hash__ 方法 # 所以我们也需要定义它 __hash__ = str.__hash__ some_dict = {...
>>> 'a' * 20 is 'aaaaaaaaaaaaaaaaaaaa' True >>> 'a' * 21 is 'aaaaaaaaaaaaaaaaaaaaa' False很不可思议,对吧?💡 解释:上面这种特性是CPython的一种编译器优化技术(叫做字符串驻留技术)。就是如果将要创建的字符串在之前已经创建过并且驻留在了内存没有释放,那么CPython不会创建一个新的实例,...

In any event, the code, being a mixture of LLM-generated code and my own rudimentary Python skills, is hardly an exemplar of efficient or elegant coding, and I am sure that there are many expert programmers who could do a much better job. But I think this is proof of concept that a...
