🐞 08_Exceptions_Debugging

Welcome to the Exceptions and Debugging section!
This module focuses on how to handle errors gracefully and find and fix bugs efficiently in your Python programs.
By mastering these concepts, you’ll learn how to make your programs more reliable and easier to maintain.

---

📘 Overview

In this section, you’ll learn:

• What exceptions are and why they occur.
• How to handle errors using try, except, else, and finally blocks.
• How to raise custom exceptions when specific conditions are not met.
• How to debug code using print statements, assertions, and Python’s built-in debugger.

🧩 Files Description

File Name	Description
01_try_except.py	Introduces the try-except structure for handling runtime errors gracefully.
02_finally_else.py	Demonstrates the use of else and finally clauses for cleaner error-handling logic.
03_raise_custom_errors.py	Shows how to raise user-defined exceptions using the raise keyword.
04_debugging_tips.py	Covers multiple debugging techniques including print(), assert, and breakpoint().

📂 Practice Folder

Practice_Exercises/

This folder includes coding exercises to help you apply what you’ve learned.
You’ll practice:

• Handling different types of errors (ZeroDivisionError, ValueError, etc.)
• Writing custom exceptions.
• Debugging faulty code to identify and fix logical or runtime bugs.

Example exercises:

• Create a program that divides two numbers safely with try-except.
• Build a temperature converter that raises an exception if invalid input is entered.
• Debug a function that incorrectly calculates totals using print() and breakpoint().

🧠 Example Code

# Example: Handling Multiple Exceptions
try:
    num = int(input("Enter a number: "))
    print("Result:", 10 / num)
except ValueError:
    print("❌ Please enter a valid number!")
except ZeroDivisionError:
    print("❌ Cannot divide by zero!")
else:
    print("✅ Operation successful!")
finally:
    print("🎯 Execution completed.")

🎯 Learning Goals

By the end of this section, you’ll be able to:

• Write error-free and fault-tolerant programs.
• Identify, handle, and raise exceptions effectively.
• Use debugging tools and techniques to locate and fix issues efficiently.
