+Getting started with ``and`` operator
+-------------------------------------
+
+Python's ``and`` operator is **binary**, which means it takes two **operands**.
+The operands in an ``and`` expression are commonly known as *conditions*.
+The result of the operator depends on the truth values of its operands. It'll
+be ``True`` if **both** are true.
