Python - How to access variable data that was set by methods

Question

I am taking a Django course on Udemy and have decided to add on to what I've learned by changing the layout of a form with an If statement.

Basically, I want to see if the BooleanField for the variable for_you is set to true (or if the check box in the GUI is checked), but I am having trouble figuring out how to access if the boolean field is set to false. Can anyone point me in the right direction?

class SignUp(models.Model):
for_you = models.BooleanField(default=True, verbose_name="Is this purchase for you? If so, check this box.")
if for_you:

Be explicit. if for_you == True or if for_you == False. Of course, if you want to keep the coding style that you have: if for_you: or if not for_you — Zizouz212

@Zizouz212 The latter is simpler, and just as clear if a more sensible variable name is chosen, e.g. if is_for_you:. — 101

@figs The former though, has the advantage of being more explicit. — Zizouz212

I think you need to tell us a bit more about the context where you're trying to access for_you.

I'm not sure if this will be helpful for you, but here's how to access for_you depending on where you are in relation to the SignUp class.

Inside a method of SignUp:

class SignUp(models.Model):

    def my_method(self):
        if self.for_you:
            # do stuff

Outside SignUp:

my_sign_up = SignUp()
if my_sign_up.for_you:
    # do stuff

I really don't know how to ask the question because my lingo isn't up to par (and thus I don't know how to look for the question despite my efforts). the for_you variable is set by an object method. I need a way of checking if the object method is true. Simply checking if for_you == True or not does not produce the desired results. I'm not sure if it makes any sense, but I'm trying ;p

Where are you checking the if for_you == True; inside the model declaration, or outside the model declaration?

The most direct way of checking if a boolean is False is using not:

if not for_you:
    print 'for_you is False!'
