Name 'xxx' is not defined

Question

Why these two function want not work ?

class Window(QtGui.QMainWindow):

 def __init__(self):
    super(Window, self).__init__()
    self.setGeometry(500, 15         


        

Answer 1

In python, it is necessary to use self to access other methods and attributes of the same object. When you simply call view_splash, python looks for the function definition but will not look at the methods of Window. By explicitly prefixing view_splash with self., python then knows that you want the method Window.view_splash and it should work as you expect.

So for your specific code, this would require you to update your run method to be the following:

def run(self):
    for i in range(len(lines)):
        n = random.choice(words)
        self.view_splash(0)
        self.view_splash(1)
        time.sleep(600)

I'm assuming that there is additional code outside of the class which defines lines and words as global variables which Window.run can then access.
