Syntax Errors occur when we violate the rules of writing the statements of the programming language. Logical Errors occur due to our mistakes in programming logic.
Program fails to compile and execute. Program compiles and executes but doesn’t give the desired output.

What are the types of error handling in Python?

There are two main error handling models: status codes and exceptions. Status codes can be used by any programming language. Exceptions require language/runtime support. Python supports exceptions.

How to catch and handle exceptions in Python?
