One of the best ways to check if your code works well is by breaking it into smaller steps. Here’s how I usually do it:
Use Test Cases: Start by creating a list of test inputs and what you expect the output to be. This helps you see if your code is doing what it should. For example, if you have a function that adds two numbers together, test it with numbers like (2, 3) and see if it gives you 5.
Boundary Values: Don’t forget to check the limit cases. These are the smallest and biggest inputs you can have, or even numbers that don’t make sense, like negative ones. For example, if your program deals with age, try using inputs like 0, 120, or a negative number to see how it responds.
Print Statements: Sometimes, just printing out what’s happening in your code can be really helpful. Print your input values, what you expect to get back, and what your code actually produces. Doing this at important moments can give you a clearer picture.
User Input Simulation: If you're using input(), try simulating what a user would do by putting some test inputs directly into your code at first. This way, you can check if your output looks right before making things more complicated.
Peer Reviews: Having someone else look at your code can help find mistakes that you might miss. They may notice errors in your logic or suggest better ways to handle input and output.
From my experience, using these techniques together can really help make sure your input and output operations are working smoothly!
