# Python program to test if all elements in list are maximum of K apart

• Last Updated : 09 May, 2021

Given a list of numbers, the task is to write a Python program to test if all elements are maximum of K apart.

Examples:

Input : test_list = [475, 503, 425, 520, 470, 500], K = 100

Output : True

Explanation : Maximum element is 520 and minimum is 425, 520-425 = 95, which is less than 100, hence elements are in range.

Input : test_list = [475, 503, 425, 540, 470, 500], K = 100

Output : False

Explanation : Maximum element is 540 and minimum is 425, 520-425 = 115, which is more than 100, hence elements are not in range.

Method #1 : Using sort()

In this, we perform the task of sorting elements to get the min and max elements accessible using sort(). The next step is to get the difference among them, if less than range, True is returned.

## Python3

 `# Python3 code to demonstrate working of``# Test if all elements are in range size``# Using sort()`` ` `# initializing list``test_list ``=` `[``475``, ``503``, ``425``, ``520``, ``470``, ``500``]`` ` `# printing original list``print``(``"The original list is : "` `+` `str``(test_list))`` ` `# initializing K``K ``=` `100`` ` `# sorting list``test_list.sort()`` ` `# checking if greater than range``res ``=` `test_list[``-``1``] ``-` `test_list[``0``] < K`` ` `# printing result``print``(``"Are elements in range ? : "` `+` `str``(res))`

Output:

```The original list is : [475, 503, 425, 520, 470, 500]
Are elements in range ? : True```

Method #2 : Using min() + max()

Instead of changing the ordering or original list, min() and max() are used to get minimum and maximum elements respectively, and the difference between them gets the required result.

## Python3

 `# Python3 code to demonstrate working of``# Test if all elements are in range size``# Using min() + max()`` ` `# initializing list``test_list ``=` `[``475``, ``503``, ``425``, ``520``, ``470``, ``500``]`` ` `# printing original list``print``(``"The original list is : "` `+` `str``(test_list))`` ` `# initializing K``K ``=` `100`` ` `# using min() and max() rather than``# changing order``res ``=` `max``(test_list) ``-` `min``(test_list) < K`` ` `# printing result``print``(``"Are elements in range ? : "` `+` `str``(res))`

Output:

```The original list is : [475, 503, 425, 520, 470, 500]
Are elements in range ? : True```
