Thetrykeyword in Python initiates exception handling blocks to gracefully manage runtime errors. Paired withexcept,else, andfinally, it prevents program crashes by capturing and processing exceptions. This tutorial covers error handling techniques with practical examples. Exception handling allows developers ...
In the example, we are trying to divide a number by0. Here, this code generates an exception. To handle the exception, we have put the code,result = numerator/denominatorinside thetryblock. Now when an exception occurs, the rest of the code inside thetryblock is skipped. Theexceptblock ...
通过继承Exception异常个类,我们可以实现用户定义的异常 class CustomException(Exception): def __init__(self, message: object): self.__message = message def inclusive_range(*args): numargs = len(args) start = 0 step = 1 # initialize parameters if numargs < 1: raise TypeError(f'expected at...
