Python 的多态不需要继承关系，靠鸭子类型就够了。它把类型检查推迟到运行时，换来的是更少的样板代码和更灵活的扩展方式。 我记得我学 Python 多态那会儿，教材上来就是"继承"、"运行时绑定"。概念堆概念，看完一章，脑子里依然一团浆糊。 后来在实际项目 ...

In Mojo, many types are defined using struct. A design feature is its nominal type system. # x, y を持つ struct が二つあっても、名前が違えば別の型（名義的） @fieldwise_init struct Point2D: var x: Int var y: Int ...

Python and Mojo have similar syntax, but they differ in their approach to values and their compile-time mechanisms. If you assume that code works the same as Python, you will encounter unexpected ...

Almost all threads in any system are waiting for resources or waiting in a ready-to-run queues to be scheduled. At any moment of time the number of running threads is equal to the number of processors ...
