# Python: Extract specified size of strings from a give list of string values using lambda

## Python Lambda: Exercise-31 with Solution

Write a Python program to extract specified size of strings from a give list of string values using lambda.

Sample Solution:

Python Code :

``````def extract_string(str_list1, l):
result = list(filter(lambda e: len(e) == l, str_list1))
return result

str_list1 = ['Python', 'list', 'exercises', 'practice', 'solution']
print("Original list:")
print(str_list1)
l = 8
print("\nlength of the string to extract:")
print(l)
print("\nAfter extracting strings of specified length from the said list:")
print(extract_string(str_list1 , l))
``````

Sample Output:

```Original list:
['Python', 'list', 'exercises', 'practice', 'solution']

length of the string to extract:
8

After extracting strings of specified length from the said list:
['practice', 'solution']
```
