Start by implementing the magic method `__bool__()`! 🔍 Define whether an instance of your class should be considered True or False when evaluated in a boolean context. Here's a simple implementation: 👇

Another way to manage truthiness is through `__len__()`! 🗂️ If `__bool__()` is not defined, Python will fall back to `__len__()`. If the length is 0, it's falsy. Example for clarity: 👇 #Python #Coding
