⚠️ Python Exception Handling for Beginners

⚠️ What is Exception Handling?

Exception Handling is a method in Python used to handle errors during program execution. It helps the program continue running instead of stopping suddenly.

Basic try-except Example

try:
    number = 10 / 0

except:
    print("Cannot divide by zero")

🔹 Why Use Exception Handling?

• Prevents program crashes
• Makes code more reliable
• Helps find and fix errors
• Improves user experience

🔹 Using Specific Exceptions

try:
    age = int(input("Enter age: "))

except ValueError:
    print("Please enter a number")

🔹 finally Block

The finally block always executes whether an error occurs or not.

try:
    print("Opening file")

finally:
    print("Program finished")

🔹 Raising Exceptions

age = -5

if age < 0:
    raise Exception("Age cannot be negative")

🚀 Practice Examples

• Handle division by zero error
• Create a calculator with error handling
• Handle wrong user input
• Handle file opening errors
