Example Analysis of raise trigger exception in python

This article will explain in detail the example analysis of raise trigger exception in python. The editor thinks it is very practical, so I share it with you for reference. I hope you can get something after reading this article.

Description

1. Directly determine whether the incoming parameter is equal to 0. If equal to 0, an exception is thrown directly, and the outer except statement captures and prints the exception information.

2. After catching an exception, if the code does not handle the exception, you can raise the exception directly in the except statement.

Example

Def calculate_num (num): try: if num = = 0: raise Exception ("the divisor cannot be 0") print (10/num) except Exception as e: print (e) calculate_num (0) this is the end of the article on "sample analysis of raise trigger exceptions in python".
