Instance attribute attribute_name defined outside __init__

Question

I split up my class constructor by letting it call multiple functions, like this:

class Wizard:
    def __init__(self, argv):
        self.parse_arguments(ar         


        

Answer 1

The best practice to solve this question is you need to build the parameter in Init part first, Then adjust it in the Def

class MainApplication(tk.Frame):
def __init__(self, master):
    self.master = master
    tk.Frame.__init__(self, self.master)
    self.settingsFrame = None
    self.create_widgets(master)

def create_widgets(self, master):
    # frame Container
    self.settingsFrame = tk.Frame(self.master, width=500, height=30, bg='white')
