How to Effectively Combine Results in Python Code

If you're working on a Python project and find yourself needing to combine results from various calculations, you're not alone. One common scenario arises when dealing with subscription fees that consist of multiple components, such as monthly fees, ad-free upgrades, and video on demand purchases. This guide explores how to effectively combine these results in your Python code.

The Problem

You might be dealing with code that iterates through different subscription accounts, calculates the fees associated with each, and prints the results. However, you notice that the final combined total across all accounts isn't being calculated correctly. Let's take a look at the original code provided and understand how it operates.

Original Code Breakdown

Here’s a snippet of the original code that computes subscription fees:

This code calculates the total for each account correctly but does not sum these totals into a combined result.

The Solution

To resolve this issue, we will make a few modifications to your existing code. Our goal is to maintain clarity and efficiency.

Steps to Combine Results

Introduce a Global Variable: We need a variable to hold the overall total of all accounts. This can be accomplished using a global variable.

Update the Function: Within the subscription_summary function, we will update this global variable with the result of each account’s total.

Print the Overall Total: At the end of our loop through accounts, we’ll print the combined total.

Updated Code

Here's the revised code incorporating the changes mentioned above:

What’s New?

The super_total variable is declared globally to store the total from all accounts.

At the end of the function, we update super_total by adding each account's total.

Finally, we print out the super_total outside of the loop.

Conclusion

Combining results in Python, especially in scenarios where multiple accounts and varied fees are involved, can be accomplished smoothly by utilizing global variables for cumulative totals. By following the outlined steps and using the updated code, you should now have a complete understanding of how to efficiently manage subscription data and calculate overall totals.
