A comparison is a yes/no value

When you compare two values, Python hands back a real True or False — a value you can store and reuse. Watch a comparison become a stored answer, and watch the boundary trip a common off-by-one.

Decide whether someone aged 18 counts as an adult (18 or older) and store the yes/no answer.

What you are looking at

Watch is_adult: a comparison turns into a stored bool.

Buggy — is_adult = age > 18 with age = 18 stores False — > excludes 18 itself. The result is a real boolean; the boundary is just wrong.
Procedural — is_adult = age >= 18 stores True. >= includes the boundary. Either way, the comparison itself is a yes/no value you can keep.

Every state you see came from running the program under CPython's tracer at build time — see how GlassBox stays honest.
