What are some effective error handling strategies in Python?

In Python, you can use try-except blocks to catch exceptions. You can also use finally to execute code regardless of whether an exception occurred.

Can you give me an example of using try-except?

Sure! Here's a simple example:

try:
    result = 10 / 0
except ZeroDivisionError:
    print('You cannot divide by zero!')

What about using custom exceptions?

You can create custom exceptions by subclassing the Exception class. For example:

class MyError(Exception):
    pass

How can I ensure that certain code runs no matter what?

You can use the finally block. It will execute after the try and except blocks, regardless of whether an exception was raised.
