Python's `int(~)` constructor returns an integer object from a string or number.

# Parameters

1. `x` | `number` or `string` | `optional`

The number or string to be converted to an integer object. Defaults to 0.

2. `base` | `number` | `optional`

The base-n literal to use when the input is a string. Valid values are 0 and 2 - 36. Default is 10.

# Return Value

An integer object.

# Examples

## Basic usage

To create an integer object from the string `'18'` :

``` a = '18'b = int(a)print(b)print(type(b)) 18<class 'int> ```

## Base parameter

To create an integer object from `'132'` (expressed in base-5):

``` a = '132'b = int(a, 5)print(b)print(type(b)) 42<class 'int'> ```

`'132'` in base-5 is the equivalent to `42` in base-10.
