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

## Python List: Exercise - 102 with Solution

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

Sample Solution:

Python Code:

``````def extract_string(str_list1, l):
result = [e for e in str_list1 if len(e) == l]
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']
```

## Python: Tips of the Day

Given a predicate function, fn, and a prop string, this curried function will then take an object to inspect by calling the property and passing it to the predicate:

Example:

```def tips_check_prop(fn, prop):
return lambda obj: fn(obj[prop])
check_age = tips_check_prop(lambda x: x >= 25, 'age')
user = {'name': 'Owen', 'age': 25}

print(check_age(user))
```

Output:

```True
```
