[FIXED] How to rapidly check object fields for emptyness

Issue

I need to check for empty values of every field of a distinct object. And I'm tiered of typing it out.

In this case. I have the an object called signal with multiple fields, which should not be empty.

if self.is_blank(signal.provider_id):
            error_response = "Signal rejected. No signal provider id given."
        elif self.is_blank(signal.sequence_id):
            error_response = "Signal rejected. No signal sequence id provided."

....

def is_blank (self, string):
        """Checks for None and empty values"""
        return True if string and string.strip() else False

Anyhow, what is the fast way in python to check all fields for "emptiness"? How do we loop them?

Solution

As rostamn mentioned, you can convert your object into a dictionary, after which you can loop through the (key, values) in a single line with a filter and check the result like so:

any_empty = any([True for x, y in your_obj.__dict__.items() if not y])

Change the condition in the loop to the type of empty check you need.
