Error Handling with Try...Except in Python

The try...except block is used for handling exceptions in Python. This allows your program to handle errors gracefully and continue execution.

Basic Try...Except Block:

Python 
try:
    x = 10 / 0
except ZeroDivisionError:
    print("Cannot divide by zero!")

# Output: Cannot divide by zero!

Handling Multiple Exceptions:

You can handle multiple exceptions by specifying different exception types in separate except blocks:

Python 
try:
    x = int("abc")
except ValueError:
    print("ValueError occurred")
except ZeroDivisionError:
    print("Cannot divide by zero!")

# Output: ValueError occurred

The Finally Block:

The finally block allows you to execute code regardless of whether an exception occurred:

Python 
try:
    x = 10 / 0
except ZeroDivisionError:
    print("Cannot divide by zero!")
finally:
    print("This code runs no matter what.")

# Output:
# Cannot divide by zero!
# This code runs no matter what.

Raising Exceptions:

You can raise an exception manually using the raise keyword:

Python 
try:
    x = -1
    if x < 0:
        raise ValueError("Negative value not allowed")
except ValueError as e:
    print(e)

# Output: Negative value not allowed

Using try...except allows you to manage errors in your programs and handle unexpected situations.
