How do I create a variable accessible by any function in a class in python?

Question

I have some code inside of a class. I want my load variable to be accessible by any function in my class, so I put my variable directly in the class. I get the error: NameError: name 'load' is not defined.

load = Image.open('obama.jpg')
def showImg(self):
    render = ImageTk.PhotoImage(load)

    img = Label(self, image=render)
    img.image = render
    img.place(x=0,y=0)

def hideImg(self):
    load.close()

Edit your question to show the class definition in which the code you posted lives. If possible, put an example of the invocation of the method and the error message as printed in the terminal. — That said, why on Earth the method is defined def hideImg(self):, I mean, does self serve any purpose? — gboffi

@gboffi The class for this code is now long gone; I am at risk of being banned from asking more questions; what can I do to reverse this risk in light of me not having the code? — Armend Veseli

Access it by self.<property_name> so in this case self.load

global load 
load = Image.open('obama.jpg')
def showImg(self):
    global load
    render = ImageTk.PhotoImage(load)

    img = Label(self, image=render)
    img.image = render
    img.place(x=0,y=0)

def hideImg(self):
    global load
    load.close()
