Error Handling with Try/Except

Sometimes, things go wrong in a program. A user might enter text when you expect a number, or you might try to divide by zero. If you don't handle these situations, your program will crash.

The try...except block lets you "try" a piece of code that might cause an error, and "catch" the error if it happens.

try:
number = int(input("Enter a number: "))
result = 10 / number
print(result)
except ValueError:
print("That wasn't a valid number!")
except ZeroDivisionError:
print("You can't divide by zero!")

In this code:
- Python first tries to run the code in the try block.
- If the user enters "abc", a ValueError occurs, and the code jumps to that except block.
- If the user enters "0", a ZeroDivisionError occurs, and it jumps to that block.
- If no error occurs, the except blocks are skipped.

This makes your programs much more robust and user-friendly.
