Using Print Statements to Find Mistakes in Your Code
When you're learning to program, especially in Year 7, it's really important to know how to fix mistakes in your code. One of the easiest and most effective ways to do this is by using print statements.
Why Use Print Statements?
See What's Happening: Print statements let you look at the values of things (like variables) at different points in your code. This can help you catch any surprises in what you're seeing.
Easy to Use: They're simple to add and don’t need any fancy tools. Just a quick line like print(variable_name) can give you useful information right away.
Track the Program's Path: By putting print statements in key spots, you can follow how your program is running.
How to Use Print Statements:
Before and After Math Operations: You can use print statements to show what's happening before you do math. Here’s an example:
print("Before addition: ", x, y)
result = x + y
print("After addition: ", result)
Checking Conditions: You can add print statements inside your if-else parts to see which way your program goes. For example:
if x > y:
print("X is greater than Y")
else:
print("Y is greater than or equal to X")
Interesting Facts:
Studies show that about half of programming mistakes are due to logic errors, which you can often find with print statements.
A poll found that 70% of new programmers mainly use print statements to fix problems they run into.
To wrap it up, print statements are a key tool for finding mistakes in code. They help students understand their work better and improve their problem-solving skills, which is essential for getting better in computer science.
