Customized Exception Handling by using try-except in Python

👉It is highly recommended to handle

     exceptions.

👉The code which may raise an exception is

     called risky code, and we have to take      

     risky code inside the try block.

👉The corresponding handling code we

      have to take inside the except block.

Syntax:

try:

    Risky Code

except XXX:

    Handling code / Alternative Code

Example:without try-except:

1. print("stmt-1")

2. print(10/0)

3. print("stmt-3")

Output:

stmt-1

ZeroDivisionError: division by zero

Abnormal termination / Non-Graceful Termination

Example:with try-except:

1. print("stmt-1")

2. try:

3. print(10/0)

4. except ZeroDivisionError:

5. print(10/2)

6. print("stmt-3")

Output:

stmt-1

5.0

stmt-3

Normal termination / Graceful Termination
