Python: Rotate a given list by specified number of items to the right or left direction
Python List: Exercise - 109 with Solution
Write a Python program to rotate a given list by a specified number of items in the right or left direction.
Sample Solution:
Python Code:
nums1 = [1, 2, 3, 4, 5, 6, 7, 8, 9, 10]
print("original List:")
print(nums1)
print("\nRotate the said list in left direction by 4:")
result = nums1[3:] + nums1[:4]
print(result)
print("\nRotate the said list in left direction by 2:")
result = nums1[2:] + nums1[:2]
print(result)
print("\nRotate the said list in Right direction by 4:")
result = nums1[-3:] + nums1[:-4]
print(result)
print("\nRotate the said list in Right direction by 2:")
result = nums1[-2:] + nums1[:-2]
print(result)
Sample Output:
original List: [1, 2, 3, 4, 5, 6, 7, 8, 9, 10] Rotate the said list in left direction by 4: [4, 5, 6, 7, 8, 9, 10, 1, 2, 3, 4] Rotate the said list in left direction by 2: [3, 4, 5, 6, 7, 8, 9, 10, 1, 2] Rotate the said list in Right direction by 4: [8, 9, 10, 1, 2, 3, 4, 5, 6] Rotate the said list in Right direction by 2: [9, 10, 1, 2, 3, 4, 5, 6, 7, 8]

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]]
