Sometimes a single block of code can produce different types of errors.
Python allows you to handle multiple exceptions in different ways.<\/p>\n\n\n\n
Handling multiple exceptions makes your program more professional and stable.<\/p>\n\n\n\n
You can handle each error separately.<\/p>\n\n\n\n
try:
num = int(input(\"Enter a number: \"))
result = 10 \/ num
except ValueError:
print(\"Invalid input. Please enter a valid number.\")
except ZeroDivisionError:
print(\"You cannot divide by zero.\")<\/pre>\n\n\n\nEach
except<\/code> block handles a specific error type.<\/p>\n\n\n\n2. HANDLING MULTIPLE EXCEPTIONS IN ONE BLOCK<\/strong><\/h2>\n\n\n\n
You can handle multiple exceptions together using parentheses.<\/p>\n\n\n\n
try:
num = int(input(\"Enter a number: \"))
result = 10 \/ num
except (ValueError, ZeroDivisionError):
print(\"Invalid input or division by zero occurred.\")<\/pre>\n\n\n\nThis is useful when you want the same message for different errors.<\/p>\n\n\n\n
3. USING GENERIC EXCEPTION (AS e)<\/strong><\/h2>\n\n\n\n
If you want to catch all types of errors:<\/p>\n\n\n\n
try:
num = int(\"abc\")
except Exception as e:
print(\"Error:\", e)<\/pre>\n\n\n\n
Exception<\/code> is the base class for most errors.e<\/code> stores the actual error message.<\/p>\n\n\n\n4. ORDER OF EXCEPT BLOCKS<\/strong><\/h2>\n\n\n\n
Always write specific exceptions first, and generic exceptions last.<\/p>\n\n\n\n
Correct order:<\/p>\n\n\n\n
try:
num = int(input(\"Enter number: \"))
result = 10 \/ num
except ValueError:
print(\"Invalid number.\")
except ZeroDivisionError:
print(\"Cannot divide by zero.\")
except Exception as e:
print(\"Other error:\", e)<\/pre>\n\n\n\nIf
Exception<\/code> is written first, specific errors will never execute.<\/p>\n\n\n\nWHY HANDLE MULTIPLE EXCEPTIONS?<\/strong><\/h2>\n\n\n\n
\u2022 Different errors need different solutions
\u2022 Makes debugging easier
\u2022 Improves user experience
\u2022 Prevents unexpected crashes<\/p>\n\n\n\nKEY POINTS<\/strong><\/h2>\n\n\n\n
\u2022 Use multiple
except<\/code> blocks for different error types
\u2022 Use(Error1, Error2)<\/code> to combine errors
\u2022 UseException as e<\/code> for general handling
\u2022 Always place general exception at the end<\/p>\n\n\n\nHandling multiple exceptions is an important step toward writing robust and professional Python programs.<\/p>\n\n\n
