Atrystatement may have more than oneexcept clause, to specify handlers for different exceptions. At most one handler will be executed. Handlers only handle exceptions that occur in the correspondingtry clause, not in other handlers of the sametrystatement. Anexcept clausemay name multiple exceptions ...
Always try to handle the exception in the code to avoid abnormal termination of the program. When creating a custom exception class, suffix its name with “Error”. If the except clauses have the same code, try to catch multiple exceptions in a single except block. ...
You use try…except blocks to handle errors. Sometimes, you use these to just log the error and continue running. Other times, you manage to recover from the error or calculate some alternative value instead.A short try…except block may look as follows:...

When you usetry…exceptin your code, it’s actually only capable of catching the first exception that occurs within thetryblock. If you try to raise multiple exceptions, the program will finish after handling the first exception. The rest will never be raised. You can show this using code ...

name multiple exceptions as a parenthesized tuple, for example: 一个:keyword:`try` 语句可能包含多个 except 子句,分别指定处理不同的异 常。至多只会有一个分支被执行。异常处理程序只会处理对应的 try 子句中发 生的异常,在同一个 :keyword:`try` 语句中,其他子句中发生的异常则不作处 ...
