How to Change Data in Range Using Python

If you're learning Python and wish to transform values in a specified range based on certain conditions, you're in the right place! This guide will guide you through the steps to change data in a range of numbers, particularly based on their divisibility by given integers.

The Problem

You have a number N, which represents the upper limit of your range, and three integers A, B, and C. The goal is to loop through every integer from 1 to N and:

Change the number to "Oke" if it's a multiple of A

Change it to "Nice" if it's a multiple of B

Change it to "Good" if it's a multiple of C

For example, if:

N = 12

A = 2

B = 3

C = 4

The output should replace the multiples with their corresponding string:

The Initial Attempt

Let’s examine the initial code shared, which had some logical issues that prevented it from functioning as intended:

Issues Identified:

Division Mistake: The code checks if the result of the division is zero (== 0), which it will never be. Instead, we should check the remainder.

Output Structure: It prints each result on a new line instead of concatenating them into a single output.

The Solution

Let’s correct the code to produce the desired output. Below is a revised version:

Explanation of the Code:

Loop Initialization: We use a loop to go through each number from 1 to N.

Conditional Checks:

We use the modulus operator % to check if the current number is a multiple of A, B, or C.

Depending on the condition met, we append the corresponding string ("Oke", "Nice", or "Good") to a list.

If none of the conditions are met, we append the number itself.

Output Generation: Finally, we transform the list of results into a single string separated by spaces and print it.

Expected Output:

Using the solution above, for N = 12, you'd get:

Conclusion

In this guide, we learned how to change data in a specified range using Python loops and conditionals. With a few tweaks, we turned an imperfect code snippet into a functional program.

Feel free to explore and modify the values of N, A, B, and C in the code to see how the output changes!

Happy Coding!
