Errors in Python:


In Python, errors are a natural part of coding and understanding and handling them correctly is a sign of a good programmer. Syntax errors are usually caught while writing the code, whereas logical and runtime errors appear during program execution. Runtime errors can be handled using exception handling, which allows your program to continue working smoothly despite errors.

Types of Errors in Python:
1. Syntax Errors: Occur when the program's code does not follow Python's rules. These are caught before execution begins.
2. Logical Errors: Occur when the program executes correctly but does not produce the expected result. These can be hard to identify as there is no explicit error message.
3. Runtime Errors (Exceptions): Occur when the program is running and an unexpected situation arises, such as division by zero or a file not being found.

Exception Handling:
In Python, exceptions are handled using `try` and `except` blocks. The code that might cause an error is placed in the `try` block, and if an error occurs, the `except` block handles it. The `else` block runs if no exception occurs in the `try` block, and the `finally` block runs in all situations, whether an exception occurred or not. This is useful for cleanup actions like closing a file.

Common Runtime Errors:
`ZeroDivisionError`, `IndexError`, `NameError`, `TypeError`, `FileNotFoundError`.
