CBSE Class 12 Computer Science one-page revision notes on Exception Handling in Python, covering syntax errors, built-in exceptions

Concept	Formula/Condition
What Can Go Wrong?	Python programs may have syntax errors, runtime errors, or logical errors. Exception handling focuses on managing exceptions.
Syntax Errors	Occur when Python rules or grammar are broken. Also called parsing errors; the program does not run until corrected.
Exceptions	Errors that occur during program execution, such as division by zero, missing files, or wrong input.
Built-in Exceptions	Common exceptions include SyntaxError, ValueError,ImportError, ZeroDivisionError, IndexError, NameError, and TypeError.
Raising Exceptions	Python raises exceptions automatically when errors occur. A programmer can also raise an exception manually using raise.
Assert Statement	assert condition tests a condition. If the condition is false, an AssertionError is raised.
Why Handle Exceptions?	Prevents programs from crashing abruptly, separates main logic from error-handling code, and helps provide proper messages to users.
