Type Errors

In Python we can classify the error in 3 ways:

Syntax Errors

Runtime Errors

Logical Errors

Syntax Errors:

Mistakes happend at user end
We can rectify manually
Ex: Mistakes at key words

Run Time Errors

Execution stops while running the program
Such type of errors syntactically accurate, but occurs errors while running the program
Ex: Division by zero, Access the file which doesn't exists

Logical Errors

Program executes correctly, but gives wrong result
Ex: Using wrong variable name

Exception Handling

When program gives abnormal termination, we can avoid this through exception handling
i.e., we need to handle the Errors with Exception
We can mention multiple errors in tuple, Except(Value Error, Zero Division Error)

Name Error:

Application throws Name Error when we provide wrong variable name

Type Error:

Occures when we provide wrong type

Value Error:

Occures when we provide wrong argument values
Occurs when it is not an integer

ZerodivisionError:

Occures when denominator is zero

Index Error:

Occures when Provided index number doesn't exists
