5.2. Integers

Python has two types of integers. Plain integers are the generic vanilla (32-bit) integers recognized on most systems today. Python also has a long integer size; however, these far exceed the size provided by C longs. We will take a look at both types of Python integers, followed by a description of operators and built-in functions applicable only to Python integer types.

5.2.1. (Plain) Integers

Python's “plain” integers are the universal numeric type. Most machines (32-bit) running Python will provide a range of -2³¹ to 2³¹-1, that is -2,147,483,648 to 2,147,483,647. Here are some examples of Python integers:

0101   84   -237   0x80   017   -680   -0X92

Python integers are implemented as (signed) longs in C. Integers are normally represented ...
