Python: Extract a given number of randomly selected elements from a given list

Python List: Exercise - 81 with Solution

Write a Python program to extract a given number of randomly selected elements from a given list.

Sample Solution:

Python Code:

import random
def random_select_nums(n_list, n):
        return random.sample(n_list, n)
n_list = [1,1,2,3,4,4,5,1]
print("Original list:") 
print(n_list)
selec_nums = 3
result = random_select_nums(n_list, selec_nums)
print("\nSelected 3 random numbers of the above list:")
print(result)

Sample Output: 

Original list:
[1, 1, 2, 3, 4, 4, 5, 1]

Selected 3 random numbers of the above list:
[4, 4, 1]

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
