# Python | Threshold Size Greater Strings Frequency

• Last Updated : 27 Feb, 2020

Sometimes, while working with huge amount of data, we can have a problem in which we need to know count of just specific sized strings which are greater than a specific length. This kind of problem can occur during validation cases across many domains. Letâ€™s discuss certain ways to handle this in Python strings list.

Method #1 : Using list comprehension + `len()`
The combination of above functionalities can be used to perform this task. In this, we iterate for all the strings and return only strings which have length greater than K checked using len(). The count is extracted using len().

 `# Python3 code to demonstrate working of``# Threshold Size Greater Strings Frequency``# using list comprehension + len()`` ` `# initialize list ``test_list ``=` `[``'gfg'``, ``'is'``, ``'best'``, ``'for'``, ``'geeks'``]`` ` `# printing original list ``print``(``"The original list : "` `+` `str``(test_list))`` ` `# initialize K ``K ``=` `3`` ` `# Threshold Size Greater Strings Frequency``# using list comprehension + len()``res ``=` `len``([ele ``for` `ele ``in` `test_list ``if` `len``(ele) >``=` `K])`` ` `# printing result``print``(``"The frequency of threshhold K sized strings are : "` `+` `str``(res))`
Output :
```The original list : ['gfg', 'is', 'best', 'for', 'geeks']
The frequency of threshhold K sized strings are : 4
```

Method #2 : Using `filter() + len()` + lambda
The combination of above functionalities can be used to perform this task. In this, we extract the elements using filter() and logic is compiled in a lambda function. The count is extracted using len().

 `# Python3 code to demonstrate working of``# Threshold Size Greater Strings Frequency``# using filter() + lambda + len()`` ` `# initialize list ``test_list ``=` `[``'gfg'``, ``'is'``, ``'best'``, ``'for'``, ``'geeks'``]`` ` `# printing original list ``print``(``"The original list : "` `+` `str``(test_list))`` ` `# initialize K ``K ``=` `3`` ` `# Threshold Size Greater Strings Frequency``# using filter() + lambda + len()``res ``=` `len``(``list``(``filter``(``lambda` `ele: ``len``(ele) >``=` `K, test_list)))`` ` `# printing result``print``(``"The frequency of threshhold K sized strings are : "` `+` `str``(res))`
Output :
```The original list : ['gfg', 'is', 'best', 'for', 'geeks']
The frequency of threshhold K sized strings are : 4
```
