# Python – Extract elements with Frequency greater than K

Given a List, extract all elements whose frequency is greater than K.

Input : test_list = [4, 6, 4, 3, 3, 4, 3, 4, 3, 8], K = 3
Output : [4, 3]
Explanation : Both elements occur 4 times.

Input : test_list = [4, 6, 4, 3, 3, 4, 3, 4, 6, 6], K = 2
Output : [4, 3, 6]
Explanation : Occur 4, 3, and 3 times respectively.

Method #1 : Using count() + loop

In this, we use count() to get the frequency, and loop is used to iterate for each of elements of List.

## Python3

 `# Python3 code to demonstrate working of  ` `# Extract elements with Frequency greater than K ` `# Using count() + loop ` ` `  `# initializing list ` `test_list ``=` `[``4``, ``6``, ``4``, ``3``, ``3``, ``4``, ``3``, ``7``, ``8``, ``8``] ` ` `  `# printing string ` `print``(``"The original list : "` `+` `str``(test_list)) ` ` `  `# initializing K  ` `K ``=` `2` ` `  `res ``=` `[]  ` `for` `i ``in` `test_list:  ` `     `  `    ``# using count() to get count of elements ` `    ``freq ``=` `test_list.count(i)  ` `     `  `    ``# checking if not already entered in results ` `    ``if` `freq > K ``and` `i ``not` `in` `res:  ` `        ``res.append(i) ` ` `  `# printing results  ` `print``(``"The required elements : "` `+` `str``(res)) `

Output

```The original list : [4, 6, 4, 3, 3, 4, 3, 7, 8, 8]
The required elements : [4, 3]
```

Method #2 : Using list comprehension + Counter()

In this, we perform the task of counting using Counter() and the iteration part is done inside list comprehension.

## Python3

 `# Python3 code to demonstrate working of  ` `# Extract elements with Frequency greater than K ` `# Using list comprehension + Counter() ` `from` `collections ``import` `Counter ` ` `  `# initializing list ` `test_list ``=` `[``4``, ``6``, ``4``, ``3``, ``3``, ``4``, ``3``, ``7``, ``8``, ``8``] ` ` `  `# printing string ` `print``(``"The original list : "` `+` `str``(test_list)) ` ` `  `# initializing K  ` `K ``=` `2` ` `  `# using list comprehension to bind result ` `res ``=` `[ele ``for` `ele, cnt ``in` `Counter(test_list).items() ``if` `cnt > K] ` ` `  `# printing results  ` `print``(``"The required elements : "` `+` `str``(res)) `

Output

```The original list : [4, 6, 4, 3, 3, 4, 3, 7, 8, 8]
The required elements : [4, 3]
```
