The TypeError exception occurs if an operation tries to perform an action with an unexpected data type. You can handle the TypeError in a try...except statement, see the example below.
A TypeError may be thrown when: an operand or argument passed to a function is incompatible with the type expected by that operator or function; or when attempting to modify a value that cannot be changed; or when attempting to use a value in an inappropriate way.
In this article, you will learn how to catch and handle TypeError exceptions using different methods in Python. TypeError is raised when you use the wrong data type in an operation. You can handle this exception using try-except blocks to prevent the program from crashing and help you correct input.
The TypeError object represents an error when an operation could not be performed, typically (but not exclusively) when a value is not of the expected type.
In Python, a TypeError occurs when an operation or function is applied to an object of an inappropriate type, such as adding a string and an integer. Although Python is dynamically typed, it still expects compatible data types for operations like arithmetic, indexing, iteration and function calls.
