Python List of lists of integers to absolute value to single number

Title: Python Tutorial: Converting a List of Lists of Integers to Absolute Values and Summing to a Single Number
Introduction:
In this tutorial, we will explore how to work with a list of lists containing integers in Python. We'll specifically focus on converting these integers to their absolute values and then summing them up to obtain a single numerical result. This can be a common operation when dealing with data processing or mathematical computations.
Requirements:
Step 1: Create a List of Lists of Integers
Let's start by creating a list of lists containing integers. Each inner list represents a set of integers.
Step 2: Use Nested Loops to Iterate Through the Lists
We need to iterate through the outer list and then through each inner list to access individual integers.
Step 3: Convert Integers to Absolute Values
Inside the nested loop, convert each integer to its absolute value using the abs() function.
Step 4: Sum Up Absolute Values
Now, let's sum up the absolute values to obtain a single numerical result. We'll use a variable to store the cumulative sum.
Step 5: Wrap it Up
You can encapsulate the logic into a function for reusability.
Conclusion:
In this tutorial, you learned how to convert a list of lists of integers to their absolute values and then sum them up to obtain a single number in Python. This process can be useful in various scenarios, such as data manipulation and mathematical operations.
