How Can I Catch and Ignore Exceptions in Python Without Writing Code Blocks?

Catching and Ignoring Exceptions in Python without Writing Code Blocks

While writing Python code, you may encounter a scenario like this:

try:
    do_the_first_part()
except SomeError:
    do_the_next_part()

Here, you want to handle the SomeError exception by executing the do_the_next_part() code. However, you don't want to write any code inside the except block because the sole purpose is to catch and swallow the exception.

To achieve this in Python, you can use the pass statement. It does not perform any action but serves as a placeholder for an empty code block. By writing pass in the except block, you satisfy the syntactic requirement for an indented block without actually executing any code.

Here's how to do it:

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

As a best practice, it's recommended to specify the exceptions you want to handle explicitly, rather than using a generic except. This way, you avoid masking potential errors that may indicate more serious issues. For example, instead of using except, consider specifying the specific exceptions you're interested in:

try:
    # Do something illegal.
    ...
except TypeError, DivideByZeroError:
    # Handle specific exceptions
    pass
