Python's `map(~)` method returns an iterator that applies the specified function to every item of an iterable.

# Parameters

1. `function` | `function`

The function to apply to each element of the iterable.

2. `iterable` | `iterable`

The iterable whose elements we will apply the function to. Multiple iterables may be specified, however, the iterator will stop when the shortest of the provided iterables is exhausted.

# Return value

An iterator that applies the provided function to every element in the iterable.

# Examples

## Basic usage

To capitalize every letter in a list:

``` letters = ['a', 'b', 'c']capitalized_letters = map(str.upper, letters)print(list(capitalized_letters)) ['A', 'B', 'C'] ```

## Lambda function

To return the cube of every number:

``` nums = [1, 2, 3, 4, 5]cube_nums = map(lambda x: x**3, nums)print(list(cube_nums)) [1, 8, 27, 64, 125] ```
