map()

Input Arguments

It takes following arguments

Argument Type	Description
function	Function over which items in iterable will be applied.
iterable	Iterable whose items will be applied to the function, like a list.

Tip

We can also pass multiple iterables as input to map().

Operation and Returns

It applies the given function to each item in the iterable and returns the response a result.
Value returned by map() function if of type map object, which can be converted to an iterable, like list.

Example

Lets take a string as input which contains a few numbers and we would like to convert it into a list of integers.
```
>>> some_list = input().split()
1 2 3 4 5
>>> some_list
['1', '2', '3', '4', '5']
>>>
```

List items are still string. So, we can use map() to convert them to integers.

>>> map_response = map(int, some_list)
>>> map_response
<map object at 0x108242310>
>>>

Here, response we get from map() is a map object. We can convert it to list.

>>> map_response_list = list(map_response)
>>> map_response_list
[1, 2, 3, 4, 5]
>>>

Tip

In short, it can be written as

>>> my_input_list = list(
...     map(
...             int,
...             input().split()
...     )
... )
1 2 3 4 5
>>> my_input_list
[1, 2, 3, 4, 5]
>>>
