How to Calculate Tax in Python: A Step-by-Step Guide

Calculating tax requires precise rules and numerical accuracy, especially in programming. This guide will walk you through how to create a Python function to compute total tax based on different brackets. Whether you're a novice coder or just looking to refine your approach, this guide will help you get it right!

The Problem: Tax Calculation Based on Earnings

You need to write a function named compute_tax(money_list) that calculates the total tax for a list of financial amounts based on the following tax brackets:

Rich individuals (earning $200 or more) pay a tax of $20.

Moderately affluent (earning between $100 and $199) pay a tax of $10.

Low earners (earning less than $100) do not pay any tax.

Example Input and Expected Output

Here are some examples of how the function should behave:

Identified Issues

Incorrect Conditional Check: The first if statement didn’t check if money was less than $200 correctly—the elif had to come first to separate the brackets.

Tax Calculation Placement: The tax variable was being increased and not reset correctly for each individual amount.

Variable Misuse: Adding tax to money is not necessary; the goal is to sum tax independently.

Revised Code

Here’s how you can fix the function:
