Using assertions for data processing and validation is a common pitfall, as you’ll learn in Understanding Common Pitfalls of assert later in this tutorial. Additionally, assertions aren’t an error-handling tool. The ultimate purpose of assertions isn’t to handle errors in production but to ...
Testing and debugging are two distinct but closely related processes. They serve different purposes and are carried out at different stages of the development lifecycle. Previously we have discussed how we can use the Python “assert” statemnet in debugging in this part of the article we will ...
将assert 声明语句作为保证条件 使用isinstance 代替 type type and isinstance in Python - GeeksforGeeks https://www.geeksforgeeks.org/type-isinstance-python/ If you’re checking to see if an object has a certain type, you want isinstance() as it checks to see if the object passed in the ...

此文是按照源码Python3.9来写,其中有些assert语句与一些不必要的宏字段会删除,保留核心的逻辑并添加注释,方便自己和大家理解。在代码中都会注明源码出处方便大家完整阅读。 Python的内存管理架构 Python是一门动态的、一切皆对象的语言,这些内存申请可能会产生大量小的内存,为了加快内存操作和减少内存碎片化,使用Python自己...
-O 开启代码优化,删掉assert与__debug__依赖的语句;在保存的.pyc文件扩展名之前,添加.opt-1字样;等价于PYTHONOPTMIZE=x -OO 不要打印版本和版权信息。这些消息在非交互模式下也被禁止。 -s 不要将用户站点目录添加到sys.path -S 启动时不引入Python的路径 -u 强制标准输出stdout与标准输入stderr流是无缓冲的...
If the assert statement fails, it will produce an error that cannot be ignored, since it halts program execution. Additionally, the error message is easy to interpret. Adding assertions to a program helps you find logical errors, and is a kind of defensive programming(防御性编程). A more fu...
