Exception handling is the process of responding to unwanted or unexpected events when a computer program runs. Exception handling deals with these events to avoid the program or system crashing, and without this process, exceptions would disrupt the normal operation of a program.
Exception handling is a mechanism that separates code that detects and handles exceptional circumstances from the rest of your program. Note that an exceptional circumstance is not necessarily an error. When a function detects an exceptional situation, you represent this with an object.
By handling multiple exceptions, a program can respond to different exceptions without terminating it. In Python, try-except blocks can be used to catch and respond to one or multiple exceptions. In cases where a process raises more than one possible exception, they can all be handled using a single except clause.
In Python, it is possible to use one-liners to set values with special conditions (such as defaults or conditions) in a simple, intuitive way.
result = 0 or "Does not exist." # "Does not exist." result = "Found user!" if user in user_list else "User not found." Is it possible to write a similar statement that catches exceptions?
from json import loads result = loads('{"value": true}') or "Oh no, explosions occurred!" # {'value': True} result = loads(None) or "Oh no, explosions occurred!" # "Oh no, explosions occurred!" is desired, but a TypeError is raised.
