AssertionError是Python中一种内建的异常,通常由assert语句引发。当你希望确保某个条件为真时,可以使用assert语句。如果条件为假,Python会自动抛出AssertionError,并附带一个可选的错误消息。这在调试和测试时尤其有用,帮助我们确保代码逻辑的正确性。 什么是AssertionError❓ 1.assert语句的作用 🧰 assert语句的基本...
出现异常(Exception)后的处理 针对不同一场设置多个expect 一个try语句可以和多个except语句使用,分别对不同的异常给出相应的处理(按照先子类后父类的顺序)。,并且针对性的写出异常处理代码。为了避免遗漏可能出现的异常,可以在最后增加BaseException。 try: sum = 1 + '1' f = open('我为什么是一个文件.txt'...
try的工作原理是,当开始一个try语句后,python就在当前程序的上下文中作标记,当异常出现时就可以回到这里,try子句先执行,接下来会发生什么依赖于执行时是否出现异常。如果当try后的语句执行时发生异常,python就跳回到try并执行第一个匹配该异常的except子句,异常处理完毕,控制流就通过整个try语句(除非在处理异常时又引发...
Python assert（断言）用于判断一个表达式，在表达式条件为 false 的时候触发异常。pytest

Python language has an in-built assert statement using which we can create simple debug message outputs that are based on logical assertions. An AssertionError exception is raised when the statement of assert fails. BaseException class is the base of all exception classes in Python. Exception clas...
