# Python – Non-overlapping Random Ranges

• Last Updated : 22 Apr, 2020

Sometimes, while working with Python, we can have problem in which we need to extract N random ranges which are non-overlapping in nature and with given range size. This can have applications in which we work with data. Lets discuss certain way in which this task can be performed.

Method : Using `any() + randint() `+ loop
This is brute force way in which this task can be performed. In this we extract random ranges using randint(), and check for non-repetition of number ranges using any() and loop.

 `# Python3 code to demonstrate working of ``# Non-overlapping Random Ranges``# Using loop + any() + randint()``import` `random`` ` `# initializing N ``N ``=` `7`` ` `# initializing K ``K ``=` `5`` ` `# Non-overlapping Random Ranges``# Using loop + any() + randint()``tot ``=` `10000``res ``=` `set``()``for` `_ ``in` `range``(N):``  ``temp ``=` `random.randint(``0``, tot ``-` `K) ``  ``while` `any``(temp >``=` `idx ``and` `temp <``=` `idx ``+` `K ``for` `idx ``in` `res):``     ``temp ``=` `random.randint(``0``, tot ``-` `K) ``  ``res.add(temp)``res ``=` `[(idx, idx ``+` `K) ``for` `idx ``in` `res]`` ` `# printing result ``print``(``"The N Non-overlapping Random ranges are : "` `+` `str``(res)) `
Output :
```The N Non-overlapping Random ranges are : [(5347, 5352), (7108, 7113), (5479, 5484), (1906, 1911), (2228, 2233), (5206, 5211), (3260, 3265)]
```
