Python Valueerror Exception

Python Valueerror Exception Python valueerror is raised when a function receives an argument of the correct type but an inappropriate value. also, the situation should not be described by a more precise exception such as indexerror. User code can raise built in exceptions. this can be used to test an exception handler or to report an error condition “just like” the situation in which the interpreter raises the same exception; but beware that there is nothing to prevent user code from raising an inappropriate error.

Python Exception Handling Valueerror The valueerror exception is often raised in python when an invalid value is assigned to a variable or passed to a function while calling it. it also often occurs during unpacking of sequence data types as well as with functions when a return statement is used. Use the most specific exception constructor that semantically fits your issue. be specific in your message, e.g.: raise valueerror('a very specific bad thing happened.') avoid raising a generic exception. to catch it, you'll have to catch all other more specific exceptions that subclass it. raise exception('i know python!') # don't!. Valueerror is a built in exception that gets raised when a function or operation receives an argument with the right type but an invalid value. it means the argument’s type is okay, but its actual value isn’t acceptable for the operation at hand. Definition and usage the valueerror exception occurs if a function receives a value of wrong type. you can handle the valueerror in a try except statement, see the example below.

Learn how to handle valueerror in python with examples. understand the causes and solutions for this common exception. Learn what a valueerror is, why it occurs, and how to handle it in python. see code examples of common scenarios where valueerror arises and how to use try and except, raise, catch, and else statements to deal with it. A try except block can be used in python programs to fix valueerror. the try block should contain the lines of code that can show the valueerror, and the except block should have the code to catch and handle the problem. A `valueerror` is typically raised when a function receives an argument of the correct type but an inappropriate value. by raising `valueerror` at the right places in your code, you can make it more self validating and easier to debug.
