what are booleans?

---

Imagine we have to divide everything into two and the options are things that are True and things that are False. These are the booleans_: True and False.

I used assertIs and assertIsNot in test_assertion_error_w_false and test_assertion_error_w_true in AssertionError, where I saw that

• False is NOT None and NOT equal to None

• True is NOT None and NOT equal to None

• None is None and equal to None

I test booleans in the chapters below

• booleans: only two
• truth table
• booleans 3: values of True and False
• booleans 4: inheritance

what is next?
