Debugging with Thonny

Debugging is an integral part of programming, and Thonny shines brightly in this area with its well-designed features aimed at making the debugging process more understandable and manageable, especially for beginners.

Thonny's debugging toolset provides functionality to set breakpoints, step through code execution, and inspect variables and expressions in real-time, all within a clean and intuitive interface. These features make it an excellent environment for understanding not only what's going wrong with your code but also how Python executes your code in general.

Let's discuss a common debugging scenario to illustrate how Thonny simplifies the debugging process.

Scenario: Suppose you are writing a Python function to calculate the factorial of a number. A factorial is the product of an integer and all the integers below it, with factorial zero being defined as 1. However, the function isn't returning the expected output.

Here's the faulty function:

def factorial(n):
    fact = 1
    for i in range(n):
        fact = fact * i
    return fact

If you call this function with the argument 5 (factorial(5)), you expect to get the output 120 (which is 54321), but instead, the function returns 0.

Debugging Process

Step 1: Set a Breakpoint To understand what's going wrong, you can set a breakpoint at the start of the for loop by clicking in the left margin of the code editor.

Step 2: Step Through the Code Next, use the "Debug" -> "Debug current script" option from the menu, or simply press F5. Thonny's debugger will stop at the first line of the for loop. Now, you can step through the code using "Step into", "Step over", and "Step out" options, or their corresponding F7, F8, and Shift+F8 shortcuts.

Step 3: Inspect Variables As you step through the code, you can watch the 'Variables' section of Thonny's interface to see the current state of your variables. You'll notice that on the first iteration of the loop, i is 0, and therefore, fact becomes 0, which is then carried through the rest of the loop, resulting in a final output of 0.

Step 4: Fix the Code Understanding the issue, you can fix the function by starting the range from 1 instead of 0:

def factorial(n):
fact = 1
for i in range(1, n+1):
fact = fact \* i
return fact

This debugging example illustrates how Thonny's debugging features not only help you spot and fix errors but also aid in understanding the underlying concepts and behaviors of Python programming. As such, Thonny's debugger is an essential tool for both learning and problem-solving.
