Python: Essential Reference, Third Edition

operator

The operator module provides functions that access the built-in operators and special methods of the interpreter described in Chapter 3. For example, add(3, 4) is the same as 3 + 4. When the name of a function matches the name of a special method, it can also be invoked using its name with double underscores—for example, __add__(3, 4).
