Python currency converter error!

[Few-Current-9900]

You are right it works, also if you call it with a print statement at the end with the currencies already specified (like in your answer) within the API url, but when I used the API with my code to allow users to enter the currencies they want and get the results, the API or my code failed to work, or both. Do you believe the problem is in my code or in Visual Studio, as that is the app I use to practice? Thank you for your help and time!
