Indent Handling in Python: Avoiding IndentationErrors

When writing Python code, it's essential to pay attention to indentation for proper execution. However, in certain scenarios, such as exception handling, one may intentionally need to leave a block empty.

In cases where you want to catch an exception but avoid executing any specific code within the exception block, Python provides a solution without triggering IndentationErrors.

How to Write Empty Indented Blocks:

To create an empty indented block, simply use the "pass" keyword:

try:
    # Do something illegal.
    ...
except Exception:
    # Pretend nothing happened.
    pass

The empty "pass" block signals to Python that you intend to catch an exception without performing any specific action within that block. This allows you to handle exceptions without code duplication or unnecessary execution.

Cautionary Note:

It's worth noting that while it's possible to create empty exception blocks, it should be used cautiously. As mentioned by @swillden, blindly catching exceptions without any specific handling can mask underlying issues or produce unexpected results.

Best practice suggests that you either handle specific types of exceptions, such as:

except TypeError, DivideByZeroError:

Or provide a custom message or raise the exception further for appropriate logging or handling.
