False is not true error?

Question

I'm trying to set global definitions to True, but I'm always getting an error saying "AssertionError: False is not True"

From instructions: 'Only things that are expected to be constant should be defined as globals. That is true for all of these.'

#global definitions
UP = True
DOWN = True
LEFT = True
RIGHT = True
dirs = [UP, DOWN, LEFT, RIGHT]

#a bunch of code follows here

This is the one of the errors (for UP) I've been getting.

self.assertTrue(isinstance(UP,Direction))
AssertionError: False is not true

I have a separate class called Direction created. Furthermore, I have to create an attribute that must be one of Up, Down, Left, and Right but I'm not sure how to do that.

attribute: value::str. Must be one of "UP", "DOWN", "LEFT", or "RIGHT".

#Direction class
class Direction:

    value = dirs

What is `Direction` and why would you expect that `UP` is of that type? — Greg Hewgill, Jul 21 '15 at 01:38
Yes, I understand what `isinstance()` does but where in your code is there anything called `Direction`? — Greg Hewgill, Jul 21 '15 at 01:41
```isinstance(UP, Direction)`` returns ```False```, and ```assertTrue(False)``` raises ```AssertionError```. It is not bug or error. — changhwan, Jul 21 '15 at 01:44
@GregHewgill I have a class called Definition created and I must include an attribute called value. Details updated above. — Vincent Luc, Jul 21 '15 at 01:48

isInstance() would return true if UP was instance of Direction. But up is not instance of Direction. it is a boolean. Hence, isinstance(UP,Direction) returns false.

Now, you are asserting that it be true. But it is not. Hence the Assertion Error, false is not true.

Change the assertTrue to assertFalse.

Your tests expects to run successful when the return value is False
