Truth, equality, and identity

Opening your lesson

A configuration value can be present even when it's zero or empty. Python treats zero, empty containers, and None as false in a condition, so a fallback written with or can erase a deliberate setting. Equality asks whether two values compare the same. Identity asks whether two names refer to the same object. Use is for a sentinel such as None, and use equality for values. Don't rely on small integer reuse or string interning. In these tasks, you'll observe identity through lists that you create yourself, classify explicit configuration inputs, and keep valid zero values in a service setting.

import json

def truth_flags(payload):
    return [bool(value) for value in json.loads(payload)]

[] == [] is True because the lists have equal contents. [] is [] is False because each expression creates a separate list. If backup = original, then backup is original is True.
