手动内存管理：C++默认情况下需要程序员显式地通过new分配内存并使用delete释放内存，否则可能导致内存泄露。
这是我的系列教程「Python+Dash快速web应用开发」的第四期，在上一期的文章中，我们进入了Dash核心内容...

*_cast 即const_cast、dynamic_cast、reinterpret_cast、static_cast。 C++风格的类型转换。dynamic_cast是动态的,需要运行时支持;其它都是静态检查,相比C风格的类型转换更加细化,增强了类型安全性。 bool,true,false bool即布尔类型,属于基本类型中的整数类型,取值为真和假。true和false分别表示真和假。注意,C语言中...

Mypy is designed with gradual typing in mind. This means you can add type hints to your code base slowly and that you can always fall back to dynamic typing when static typing is not convenient. Mypy has a powerful and easy-to-use type system, supporting features such as type inference,...
This feature makes it possible to handle large data stream, OpenAI integrations, deliver dynamic content, and support other core HTTP scenarios requiring real-time interactions over HTTP. You can also use FastAPI response types with HTTP streams. Without HTTP streams, the size of your HTTP ...

Mypy is a static type checker for Python. Type checkers help ensure that you're using variables and functions in your code correctly. With mypy, add type hints (PEP 484) to your Python programs, and mypy will warn you when you use those types incorrectly. Python is a dynamic language, ...
