I’m currently working on a Banking System project in Python. While building it, I realized that I can break down every single feature (like Login, Withdrawal, or Deposit) into three distinct stages:</p> <p><strong>INPUT</strong>: Getting data from the user.</p> <p><strong>PROCESS</strong>: Calculating or validating that data.</p> <p><strong>OUTPUT</strong>: Displaying the result or a message.</p> <p>My questions for the community are:</p> <ul> <li><p>Is this IPO model the true foundation of all programming, regardless of project size?</p></li> <li><p>Is it 'safe' to rely on this mindset for my entire learning journey and coding life ?</p></li> </ul> <p><strong>I’d love to hear if there are other professional frameworks I should keep in mind as I grow. Thanks!"</strong></p> programming beginners python architecture
