try:
print(10/0)
except ZeroDivisionError as msg:
print("exception raised and its description is:", msg)
Output:
exception raised and its description is: division by zero
try with multiple except blocks:
👉The way of handling exception is varied from exception to exception.
👉Hence,we have to provide separate except block for every exception type.
👉That is, try with multiple except blocks is possible and recommended to use.
Example:
try:
------
------
------
except ZeroDivisionError:
perform alternative arithmetic operations
except FileNotFoundError:
use local file instead of remote file
👉If try with multiple except blocks available, then based on the raised exception, the corresponding except block will be executed.
Example: Multiple except blocks in Python
try:
x = int(input("Enter First Number: "))
y = int(input("Enter Second Number: "))
print(x / y)
except ZeroDivisionError:
print("Can't Divide with Zero")
except ValueError:
print("please provide int value only")
Program Execution:
D:\Python3>py Multi.py
Enter First Number: 10
Enter Second Number: 5
2.0
D:\Python3>py Multi.py
Enter First Number: 10
Enter Second Number: 0
Can't Divide with Zero
D:\Python3>py Multi.py
Enter First Number: 10
Enter Second Number: five
please provide int value only
✅Note: If try has multiple except blocks, the order of the except blocks is important.
👉The Python interpreter always checks from top to bottom and executes the first matching except block.
Example
1) try:
2) x = int(input("Enter First Number: "))
3) y = int(input("Enter Second Number: "))
4) print(x / y)
5) except ArithmeticError:
6) print("ArithmeticError")
7) except ZeroDivisionError:
8) print("ZeroDivisionError")
D:\Python3> py MulEx.py
Enter First Number: 5
Enter Second Number: 0
ArithmeticError
✅Note:
Since ZeroDivisionError is a subclass of ArithmeticError, the except ArithmeticError block will catch it first. That’s why exception order matters in Python.
