Catch any error in Python

Question

Is it possible to catch any error in Python? I don\'t care what the specific exceptions will be, because all of them will have the same fallback.

Answer 1

try:
    # do something
except Exception, e:
    # handle it

For Python 3.x:

try:
    # do something
except Exception as e:
    # handle it

Answer 2

Built-In Exceptions in Python

Built-In exception classes are divided into Base error classes from which the error classes are defined and Concrete error classes which define exceptions which you are more likely to see time to time.

The more detailed document about the buit-In exception can be found in [https://docs.python.org/3/library/exceptions.html]

Custom Exceptions

It is used to fit your specific application situation. For example, you can create your own exception as RecipeNotValidError as the recipe is not valid in your class for developing a cooking app.

Implementation

class RecipeNotValidError(Exception):    
    def __init__(self):       
        self.message = "Your recipe is not valid"        
        try:            
            raise RecipeNotValidError
        except RecipeNotValidError as e:            
            print(e.message)

These are custom exceptions that are not defined in the standard library. The steps you can follow to create custom classes are :

1. Subclass the Exception class.
2. Create a new Exception class of your choice.
3. Write your code and use the try...except flow to capture and handle your custom exception.
