设计模式是面对各种问题进行提炼和抽象而形成的解决方案。这些设计方案是前人不断试验,考虑了封装性、复用性、效率、可修改、可移植等各种因素的高度总结。它不限于一种特定的语言,它是一种解决问题的思想和方法 为什么要用设计模式 按照设计模式编写的代码,其可读性也会大大提升,利于团队项目的继承和扩展。 回到顶部...
Your first encounter with an exception group is likely to be its traceback. Exception group tracebacks are formatted to clearly show you the structure within the group. You’ll see a traceback when you raise an exception group:Python >>> raise ExceptionGroup("nested", ... [ ... ...

We have also PEP-8 code guidelines that help structure our code. It’s a must for me, with some appropriate exceptions, of course. By the way, these exceptions are encouraged by PEP-8 itself: But most importantly: know when to be inconsistent – sometimes the style guide just doesn’t ...
https://docs.python-guide.org/writing/structure/ 19. 如果实现容易描述,那可能是个好方案 使设计(甚至人们的生活)更容易,即使背景知识可能很深刻,这是编程的专业知识,我认为也是编程中最困难的部分。 利用Python 的简单性和可读性来实现一些疯狂的想法。

• Nested exception/interrupt support • Vectored exception/interrupt entry • Interrupt masking 异常包含中断。中断时异常的一部分,中断通常有外围设备:定时器、看门狗、ADC、spi等 ,也可以由引脚来触发。 (有时候会问到是芯片内部外设或者Cotex-M的外设,芯片内部外设例如:SPI、I2C、串口、内部FLASH、ADC、...
