python program to left rotate a list by n

Title: Python Tutorial - Left Rotate a List by N
Introduction:
In this tutorial, we will explore how to left rotate a Python list by N positions. Left rotation of a list means that the elements at the beginning of the list are moved to the end, and the elements at the end are shifted to the beginning.
Let's dive into the implementation with a step-by-step explanation and a code example.
Step 1: Understand the Problem
To left rotate a list by N positions, we need to take the first N elements from the beginning of the list and move them to the end. The remaining elements will be shifted to the beginning.
Step 2: Plan the Solution
We can achieve the left rotation by using list slicing. We'll take the first N elements from the list and concatenate them with the remaining elements.
Step 3: Implement the Solution
Step 4: Test the Function
Now, let's test the function with an example:
This should output:
Conclusion:
In this tutorial, we covered how to left rotate a Python list by N positions using list slicing. The left_rotate_list function can be easily integrated into your programs whenever left rotation of a list is needed. Feel free to customize the code according to your specific requirements.
