Python – Nth smallest Greater than K
• Last Updated : 27 Feb, 2020

This article offers various approaches to solve the problem of finding Nth smallest number in python list greater than a specific element K in python list. This basically provides all the approaches from naive to one-liners so that they can be used in programming whenever required.

Method 1 : Naive Method + `sort()`
Using loop we keep on adding elements that are greater than K and then sort the list and find the Nth element greater than K.

 `# Python 3 code to demonstrate ``# Nth smallest Greater than K``# using naive method + sort()`` ` `# Initializing list ``test_list ``=` `[``1``, ``4``, ``7``, ``5``, ``10``]`` ` `# Initializing k``k ``=` `6`` ` `# Initializing N ``N ``=` `2`` ` `# Printing original list ``print` `(``"The original list is : "` `+` `str``(test_list))`` ` `# Using naive method + sort()``# Nth smallest Greater than K``res ``=` `[]``for` `i ``in` `test_list :``    ``if` `i > k :``        ``res.append(i)``res.sort()`` ` `# Printing result ``print` `(``"The Nth minimum value greater than 6 is : "` `+` `str``(res[N ``-` `1``]))`
Output :
```The original list is : [1, 4, 7, 5, 10]
The Kth minimum value greater than 6 is : 10
```

Method 2 :` lambda + filter() + sort()`
Similar approach to method above, just to filter the numbers in list greater than k, filter() instead of loop is used in this approach. Works in a similar way as above after that.

 `# Python 3 code to demonstrate ``# Nth smallest Greater than K``# using min() + sort() + lambda`` ` `# Initializing list ``test_list ``=` `[``1``, ``4``, ``7``, ``5``, ``10``]`` ` `# Initializing k``k ``=` `6`` ` `# Initializing N ``N ``=` `2`` ` `# Printing original list ``print` `(``"The original list is : "` `+` `str``(test_list))`` ` `# Nth smallest Greater than K``# using min() + sort() + lambda``res ``=` `list``(``filter``(``lambda` `i: i > k, test_list))``res.sort()`` ` `# Printing result ``print` `(``"The Nth minimum value greater than 6 is : "` `+` `str``(res[N ``-` `1``]))`
Output :
```The original list is : [1, 4, 7, 5, 10]
The Kth minimum value greater than 6 is : 10
```
