Abstract
This chapter introduces expressions, literals, operators, identifiers, binding and module importing, by illustrating how Python can be used as a calculator. Three mathematical modules, including math, cmath and random, are introduced, which enable more mathematical calculations than built-in operators.

Notes
- 1.
The content after the # symbols are comments and can be ignored when typing the examples. Details about comments are given in Chap. 3 or the rest of the book \(>>>\) indicates an IDLE command.
- 2.
The memory addresses in the examples below are unlikely to be reproduced when the examples are tried again, since the allocation of memory addresses is dynamic and runtime dependent.
- 3.
Exactly which small values are represented as frequently accessed objects depends on the Python distribution.
