# Catch any exception and print the exception message print(f"An error occurred: {e}") Output: An error occurred: division by zero Explanation: 'Exception' is the base class for all built-in exceptions. By catching 'Exception', you can handle any kind of error. 'as e' allows you to ...
try:do_something()except Exception:# THis will catch any exception!print("Something terrible happened") 为了合理准确的定义你的异常类,这里有一些规范与编程技巧,你可以做为参照: 必须继承 Exception类: class MyOwnError(Exception): pass 利用前面提到的BaseException.str: 它将传递给BaseException.init方法的...
可以指定内置异常类类型,采用匿名类型,不获取异常信息print'catch IOError.'except TypeError aserror: #捕获异常定义异常变量,新的API采用'as'来指定变量名称.print'catch TypeError.',errorexcept (UnboundLocalError,BufferError): #捕获异常定义捕获的异常类型可以使用元组的形式添加多个捕获的...
print("An exception occurred:", e) 3. Catching Multiple Exceptions with Tuple Using a tuple of exception types is a simple and concise way to catch multiple exceptions in a singleexceptblock in Python. When an exception occurs in thetryblock, Python checks if the exception is an instance of...
该种定义异常变量的方法属于老的api,新的api向下兼容.print"catch Exception and use \',\' define param.",errorexcept:#捕获所有的异常类型包括系统异常退出等.passelse:#else为未发生异常执行的代码块,必须在except之后print"no catch any Exception."finally:#finally不管有没有出现异常均会执行,可以和try单独...
If an exception is raised due to the code in the try block, the execution continues with the statements in the except block. So, it is up to the programmer how to handle the exception. The plain try-except block will catch any type of error. But, we can be more specific. For instan...
In the except block, along with the keyword except we can also provide the name of exception class which is expected to occur. In case we do not provide any exception class name, it catches all the exceptions, otherwise it will only catch the exception of the type which is mentioned....
Exception groups will group together exceptions that are unrelated, in the sense that they happen independently of each other. When handling chained exceptions, you’re only able to catch and handle the last error in the chain. As you’ll learn soon, you can catch all the exceptions in an ...
