Tools and Techniques for Debugging

There are several tools and techniques that you can use to debug your Python code, including:

In this example, we'll walk you through how to debug a simple calculator program using Python. The program takes two numbers and one operator (+, -, x, /) as input and returns the result.

def calculator(num1, num2, operator):
    if operator == '+':
        return num1 + num2
    elif operator == '-':
        return num1 - num2
    elif operator == 'x':
        return num1 * num2
    elif operator == '/':
        if num2 != 0:
            return num1 / num2
        else:
            print("Error: Division by zero")
            return None

# Test the calculator
print(calculator(5, 3, '+'))  # Output: 8
print(calculator(5, 3, '-'))  # Output: 2
print(calculator(5, 3, 'x'))  # Output: 15
print(calculator(5, 3, '/'))  # Output: 1.6666666666666667
print(calculator(5, 0, '/'))  # Output: Error: Division by zero
