Quick Answer

Manage errors gracefully with try-except blocks.

Understanding the Issue

Python uses try-except blocks to handle exceptions. The else clause runs when no exception occurs, while finally always executes. Be specific in catching exceptions to avoid masking bugs.

The Problem

This code demonstrates the issue:

Python Error 
# Risky operation that might fail
result = 100 / user_input

The Solution

Here's the corrected code:

Python Fixed 
try:
    result = 100 / float(user_input)
except ZeroDivisionError:
    print("Cannot divide by zero!")
except ValueError:
    print("Invalid number")
else:
    print("Result:", result)
finally:
    print("Operation attempted")

Key Takeaways

Catch specific exceptions and clean up in finally.
