# Python – Keys Frequency with Value atmost K

Sometimes, while working with Python dictionaries, we can come across a problem in which we have a particular value, and we need to find frequency if it’s occurrence and value is atmost K. Let’s discuss certain ways in which this problem can be solved.

Method #1 : Using loop
This problem can be solved using naive method of loop. In this we just iterate through each key in dictionary and when a match is found, the counter is increased.

 `# Python3 code to demonstrate working of ` `# Keys Frequency with Value atmost K ` `# Using loop ` ` `  `# Initialize dictionary ` `test_dict ``=` `{``'gfg'` `: ``1``, ``'is'` `: ``2``, ``'best'` `: ``3``, ``'for'` `: ``4``, ``'CS'` `: ``5``} ` ` `  `# printing original dictionary ` `print``(``"The original dictionary : "` `+` `str``(test_dict)) ` ` `  `# Initialize value  ` `K ``=` `3` ` `  `# Using loop ` `# Keys Frequency with Value atmost K ` `res ``=` `0` `for` `key ``in` `test_dict: ` `    ``if` `test_dict[key] <``=` `K: ` `        ``res ``=` `res ``+` `1` `     `  `# printing result  ` `print``(``"Frequency of keys with values till K is : "` `+` `str``(res)) `

Output :

```The original dictionary : {'CS': 5, 'is': 2, 'gfg': 1, 'best': 3, 'for': 4}
Frequency of keys with values till K is : 3
```

Method #2 : Using `sum() + values()`
This can also be solved using the combination of sum() and value(). In this, sum is used to perform the summation of values filtered and values of dictionary are extracted using values().

 `# Python3 code to demonstrate working of ` `# Keys Frequency with Value atmost K ` `# Using sum() + values() ` ` `  `# Initialize dictionary ` `test_dict ``=` `{``'gfg'` `: ``1``, ``'is'` `: ``2``, ``'best'` `: ``3``, ``'for'` `: ``4``, ``'CS'` `: ``5``} ` ` `  `# printing original dictionary ` `print``(``"The original dictionary : "` `+` `str``(test_dict)) ` ` `  `# Initialize value  ` `K ``=` `3` ` `  `# Using sum() + values() ` `# Keys Frequency with Value atmost K ` `res ``=` `sum``(x <``=` `K ``for` `x ``in` `test_dict.values()) ` `     `  `# printing result  ` `print``(``"Frequency of keys with values till K is : "` `+` `str``(res)) `

Output :

```The original dictionary : {'CS': 5, 'is': 2, 'gfg': 1, 'best': 3, 'for': 4}
Frequency of keys with values till K is : 3
```
