Python: Access multiple elements of specified index from a given list

Python List: Exercise - 111 with Solution

Write a Python program to access multiple elements at a specified index from a given list.

Sample Solution:

Python Code:

def access_elements(nums, list_index):
    result = [nums[i] for i in list_index]
    return result


nums = [2,3,8,4,7,9,8,2,6,5,1,6,1,2,3,4,6,9,1,2]
print ("Original list:")
print(nums)
list_index = [0,3,5,7,10]
print("Index list:")
print(list_index)
print("\nItems with specified index of the said list:")
print(access_elements(nums, list_index))

Sample Output: 

Original list:
[2, 3, 8, 4, 7, 9, 8, 2, 6, 5, 1, 6, 1, 2, 3, 4, 6, 9, 1, 2]
Index list:
[0, 3, 5, 7, 10]

Items with specified index of the said list:
[2, 4, 9, 2, 1]

Python: Tips of the Day

Chunks a list into smaller lists of a specified size:

Example:

from math import ceil

def tips_chunk(lst, size):
  return list(
    map(lambda x: lst[x * size:x * size + size],
      list(range(0, ceil(len(lst) / size)))))

print(tips_chunk([1, 2, 3, 4, 5, 6], 3))

Output:

[[1, 2, 3], [4, 5, 6]]
