debian/ubuntu apt program

[jtmtman]

I've been able to copy/paste my way to a semi completed program. It helps with with the apt command, displays descriptions of the packages, download package.

Right now its set for a 'dry run' and is in a testing mode. Please tell me if i am doing anything wrong. I'm sure i could be doing some things a better way. Let me know. Thanks.

    pword = 'YOURPASSWORD'
    app = SampleApp()
    app.mainloop()

The things i want to work on are a pop-up window for a password prompt and being able to clear the scrollable frame.
I tried using the pack_forget() method but was unsuccessful.

This is what i  tried for the new window with the password prommpt.

        def confirm_pass(self, pass_get):
            print(pass_get)
            
        def get_pass(self):
            top = Toplevel()
            l = Label(top, text="Enter Password:")
            l.pack()
            pass_ent = Entry(top)
            pass_ent.pack()
            pass_get = pass_ent.get()
            b = Button(top,text = "Search",command = self.confirm_pass(pass_get))
            b.pack()

Rather than including your whole project, could you write up a minimal snippet of code for your specific question(s)? This would probably be 20 or less lines of code, and the simplification would increase the chance of a helpful reply. (I don't do GUI code, so I'm minimally qualified to help here anyway.)
