Python -- Checking a list of objects to see if any have a specific attribute values

Question

Is there any way of checking through a list of objects to see if any of them have a specific value for an attribute (or attributes). Let's say you wanted a program to see if there were any cabinets in a list of cabinets that were 40 inches tall and 50 inches wide. Does python have a way of finding that?

You can use a list comprehension:

object_with_specific_attribute = [obj for obj in object_list if obj.length == 40 and obj.width == 50]

OP's question doesn't necessarily request for a list of objects that satisfy the criteria -- You could probably get away with an any(generator_expression) if short-circuiting is desired and only a boolean result is required.

And a very trivial nitpick: I would rename it objects_with_specific_attribute (note, objects, not `object) to indicate that you have a sequence and not a scalar.
