int data type

int data type represents the numbers that are in the range -2147483648 through 2147483647. The numbers that are outside of this range are normally called long integers.

Numbers are created by numeric literals or as the result of built-in functions and operators. Plain integer literals (including binary, hex, and octal numbers) yield plain integers unless the value they denote is too large to be represented as a plain integer, in which case they yield a long integer. Integer literals with an ‘L’ or ‘l’ suffix yield long integers (‘L’ is preferred because 1l looks too much like eleven! :0).

Constructors

int(): It converts an expression into an integer.
literal syntax: It is used to initialize a new instance of the int type. e.g.

>>> 7
7
>>> 7+7
14
>>> 2**30
1073741824
>>> -1073741824
-1073741824

Examples

Valid integer literals:

>>> 0
0
>>> 7
7
>>> -13
-13
>>> 135792468
135792468
>>> y=50000000000000000000000000000
50000000000000000000000000000

Binary, octal, and hexadecimal

>>> 0b11011000 # binary
