异常即是一个事件,该事件会在程序执行过程中发生,影响了程序的正常执行。 一般情况下,在Python无法正常处理程序时就会发生一个异常。 异常是Python对象,表示一个错误。 当Python脚本发生异常时我们需要捕获处理它,否则程序会终止执行。 异常处理 捕捉异常可以使用try/except语句。 try/except语句用来检测try语句块中的错...
Python provides a robust mechanism for catching and handling exceptions, enabling developers to create resilient programs that can manage unexpected situations effectively. What are the Different Types of Errors and Exceptions in Python? Python categorizes errors and exceptions into several types, each ...
Python Tutorial 学习(八)--Errors and Exceptions恢复 Errors and Exceptions 错误与异常 此前,我们还没有开始着眼于错误信息.不过如果你是一路跟着例程走过来的,你就会发现一下错误信息.在Python里面至少有两类错误:语法错误和异常(syntax errors and exceptions) 8.1. Syntax Errors 语法错误 语法错误就是语法错误,...
Even if a statement or expression is syntactically correct, it may cause an error when an attempt is made to execute it. Errors detected during execution are calledexceptionsand are not unconditionally fatal: you will soon learn how to handle them in Python programs. Most exceptions are not han...
为了方便大家对照学习,所以先附上本节课对应的官网链接:https://docs.python.org/3.6/tutorial/errors.html 虽然之前没有系统讲解过错误信息,但是如果认真进行过代码实践,则必然不时会产生一些错误信息。至少有两种显著的错误:语法错误和异常(所以一定要搞清这三者之间的逻辑关系)。
我们的程序在遇到错误之后,会给出一个错误名称(异常名称),上面代码中的ZeroDivisionError、NameError、TypeError就是python这门语言中的内置异常名称,他们通常以Error结尾。如果想知道还有哪些内置异常,可以点击这里查看:Built-in Exceptions 了解了异常名称之后,我们来学习如何利用他们。
