What is ValueError in Python ?


Another example of ValueError is when you try to call the range() function with an invalid argument. For instance, the range() function expects one or more integers as arguments, and if you pass a float or a string, it will raise a ValueError:

python
Copy code
>>> range(1.5)

In Python, a ValueError is a type of exception that is raised when an operation or function receives an argument that has the correct type but an inappropriate value.

For example, if you try to convert a string that does not represent a valid number to an integer using the int() function, a ValueError will be raised because the string cannot be converted to an integer:

python
Copy code
>>> int(\’hello\’)
ValueError: invalid literal for int() with base 10: \’hello\’
ValueError: range() integer end argument expected, got float.

Overall, a ValueError indicates that there is a problem with the input value passed to a function or operation, and it helps to identify and fix the problem.
