How to Rotate Python Lists Clockwise and Counterclockwise?

Rotating Python Lists

In Python, rotating a list refers to shifting its elements right or left by a specified number of positions. To accomplish this, you can utilize the following functions:

Clockwise Rotation:

<code class="python">def rotate_clockwise(l, n):
    return l[-n:] + l[:-n]</code>

Here, n represents the number of positions to rotate the list to the right. This function isolates the last n elements and places them at the beginning, effectively rotating the list clockwise.

Counterclockwise Rotation:

<code class="python">def rotate_counterclockwise(l, n):
    return l[n:] + l[:n]</code>

Similar to the previous function, this one rotates the list counterclockwise by shifting elements n positions to the left.

Example Usage:

<code class="python">example_list = [1, 2, 3, 4, 5]

rotate_clockwise(example_list, 2) # [3, 4, 5, 1, 2]
rotate_counterclockwise(example_list, 2) # [2, 3, 4, 5, 1]</code>

These functions operate on copies of the input list, ensuring that the original list remains unchanged. The arguments l and n specify the list to be rotated and the number of positions to shift, respectively.
