# Python | Values Frequency till Maximum K

One of the problem that is basically a subproblem for many complex problem, finding numbers smaller than certain number in list in python, is commonly encountered and this particular article discusses possible solutions to this particular problem.

Method 1 : Naive method
The most common way this problem can be solved is using loop and just counting the occurrences of elements that are smaller than the given number K.

 `# Python 3 code to demonstrate  ` `# Values Frequency till Maximum K ` `# using naive method  ` ` `  `# initializing list ` `test_list ``=` `[``1``, ``7``, ``5``, ``6``, ``3``, ``8``] ` ` `  `# initializing k ` `k ``=` `4` ` `  `# printing list  ` `print` `(``"The list : "` `+` `str``(test_list)) ` ` `  `# using naive method  ` `# to get numbers < k ` `count ``=` `0` `for` `i ``in` `test_list : ` `    ``if` `i < k : ` `        ``count ``=` `count ``+` `1` ` `  `# printing the result ` `print` `(``"The numbers smaller than 4 : "` `+` `str``(count)) `

Output :

```The list : [1, 7, 5, 6, 3, 8]
The numbers smaller than 4 : 2
```

Method 2 : Using `sum()`
The sum() can also help us achieving this task. We can return 1 when the number smaller than k is found and then compute the summation of is using sum().

 `# Python 3 code to demonstrate  ` `# Values Frequency till Maximum K ` `# using sum() ` ` `  `# initializing list ` `test_list ``=` `[``1``, ``7``, ``5``, ``6``, ``3``, ``8``] ` ` `  `# initializing k ` `k ``=` `4` ` `  `# printing list  ` `print` `(``"The list : "` `+` `str``(test_list)) ` ` `  `# using sum() ` `# to get numbers < k ` `count ``=` `sum``(i < k ``for` `i ``in` `test_list) ` ` `  `# printing the result ` `print` `(``"The numbers smaller than 4 : "` `+` `str``(count)) `

Output :

```The list : [1, 7, 5, 6, 3, 8]
The numbers smaller than 4 : 2
```
