How to Sum Positive Integers with Python: A Beginner’s Guide

Hello, fellow coding enthusiasts! Today, we’re diving into a fundamental Python exercise that many beginners face: creating a program to sum a series of positive integers while excluding any integers greater than 100. If you’re just starting in programming, this exercise is a great way to not only understand conditionals but also to practice user input and debugging.

The Problem Statement

In simple terms, the goal is to write a Python program that:

Accepts positive integer inputs from the user.

Sums these integers only if they are 100 or lower.

Provides feedback when the input values are invalid (i.e., negative numbers or numbers greater than 100).

Breaking Down the Solution

Let’s analyze the solution for clarity and organization. Below is an improved version of the initial code shared by a community member, with comments to explain the logic clearly.

Step-by-step Code Explanation

Key Concepts Explained

User Input: The program receives integers through the input() function, which is essential for any interactive program.

Conditional Statements: We use if statements to validate the user’s input. If the input is either greater than 100 or negative, we ignore that input and notify the user.

Total Calculation: We maintain a total variable to keep a running sum of valid integers. Only numbers that meet the criteria are added to this total.

Output Results: Finally, the program prints the total of the valid inputs, or if no valid inputs were given, it still provides the output accordingly.

Conclusion

This Python exercise not only strengthens your coding skills but also emphasizes error handling and input validation, which are crucial in creating robust applications. Feel free to expand this code to accept more integers or even implement loops to keep asking the user until they decide to stop.

Now it’s your turn! Try running this program, add some enhancements, or integrate it into a larger project. Happy coding!
