How to Rotate an Array by k Steps in Python

This code rotates a list to the right by k positions using modulo arithmetic to handle k larger than the list length.

Python 
def rotate_array(nums, k):
    if not nums:
        return []
    n = len(nums)
    k = k % n
    return nums[-k:] + nums[:-k] if k else nums[:]

if __name__ == "__main__":
    arr = [1, 2, 3, 4, 5, 6]
    k = 2
    result = rotate_array(arr, k)
    print(f"Original: {arr}")
    print(f"Rotated by {k}: {result}")
