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 specified number of items to 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]
