Introduction

This lesson is part of our complete Python course for beginners. In this lesson, you will learn exception handling in Python and how to handle errors in your programs.

Understanding exception handling in Python for beginners is important because it helps you write error-free and stable applications.

What is Exception Handling in Python?

Exception handling in Python is used to handle runtime errors so that the program does not crash.

Types of Errors in Python

• Syntax Errors
• Runtime Errors
• Logical Errors

Try and Except Block

You can handle errors using try and except.

Example:

try:
x = int(“abc”)
except:
print(“Error occurred”)

Using Specific Exceptions

try:
x = int(“abc”)
except ValueError:
print(“Invalid input”)

Finally Block

The finally block always executes.

Example:

try:
x = 10 / 2
except:
print(“Error”)
finally:
print(“Execution completed”)

Raising Exceptions

You can raise exceptions manually using raise.

Example:

x = -1
if x < 0:
raise ValueError(“Negative value not allowed”)

Why Exception Handling is Important

Exception handling in Python helps you:

• Prevent program crashes
• Handle unexpected errors
• Improve user experience

Therefore, understanding exception handling in Python for beginners is essential.
