8 Python Try Except

1. What is Try Except?

Try Except is used to handle errors in Python.

In simple words:
👉 Python tries to run the code
👉 If an error happens, Python does not crash
👉 Instead, it runs the except code

2. Why Use Try Except?

Without try-except:

• Program stops suddenly

• User sees error message

With try-except:

• Program continues

• We can show friendly message
