Distributing a List into Different Length Lists in Python: A Step-by-Step Guide

Have you ever needed to divide a list into multiple smaller lists of varying lengths while maintaining the original order of the elements? If so, you're not alone! In this guide, we’ll explore how to take a single list with 12 elements and separate it into three lists of different lengths—4, 3, and 5 elements, respectively—using Python.

The Problem

Let's say you have an original_list containing 12 elements, and you wish to distribute these elements into three lists:

List 1: Should contain 4 elements.

List 2: Should include 3 elements.

List 3: Should consist of 5 elements.

But there’s a catch: you want to maintain the order of elements as you distribute them, cycling through the lists repeatedly. This means that the first element goes to List 1, the second to List 2, the third to List 3, the fourth back to List 1, and so on.

For example, the distribution should look like this:

original_list[0] → list1[0]

original_list[1] → list2[0]

original_list[2] → list3[0]

original_list[3] → list1[1]

And so forth...

The Solution

We can achieve this using a simple Python program. Below, I will break down the solution into manageable parts.

Step 1: Initialize the Lists

First, we will create our original_list and initialize the target lists (list1, list2, list3) to store the distributed elements.

Step 2: Iterate Over the Original List

Next, we need to loop through the original_list in steps of 3. This is because we want to fill each of the lists one element at a time. The conditions inside the loop will check which list to append each element to.

Step 3: Append Elements to Corresponding Lists

Using conditions based on the length of each list, we can determine where to place the elements as we iterate through the original_list.

The Complete Code

Here’s the program that demonstrates the described logic:

Explanation of the Code

Initialization: The original_list consists of integers 1 through 12. We also created empty lists list1, list2, and list3 to hold our data.

Looping and Conditions: The for loop iterates through indices of original_list, and we use conditions to check the length of list1 and list2. This ensures we don't fill these lists beyond their maximum capacity.

Appending: Elements from original_list are appended to the appropriate list based on the iteration.

End Result

When you run this code, it will output the following:

list1 has 4 elements

list2 has 3 elements

list3 has 5 elements

Conclusion

Using the method outlined above, you can effectively distribute a single list into multiple lists of varying lengths while maintaining the original order and cycling through the lists. This approach can be tailored to different sizes and distributions based on your needs. Happy coding!
