Retrieve input from Entry widget stored as an instance variable and use it outside of the class

I have difficulties trying to get the input from Entry widget stored as a instance variable, so I can use it as input outside this class:

class CreateGUI:

    def __init__(self, master):
        self.master = master
        self.master.geometry("275x325")
        self.master.columnconfigure(0, weight=1)
        self.master.columnconfigure(1, weight=2)
        self.checkbutton_var1 = IntVar()
        self.checkbutton_var2 = IntVar()
        self.path = ''
        self.type = []

    def add_labels(self):
        Label(self.master, text="Provide path to file:").grid(column=0, row=0, padx=10, pady=10, sticky="N")

    def add_entries(self):
        user_input = Entry(self.master)
        user_input.grid(column=0, row=1, padx=5, pady=5, ipadx=60)
        return user_input

    def add_buttons(self, user_input):
        checkbutton1 = Checkbutton(self.master, text="test1", variable=self.checkbutton_var1, onvalue=1,offvalue=0,height=2,width=10)
        checkbutton1.grid(column=1, row=0)
        checkbutton2 = Checkbutton(self.master, text="test2", variable=self.checkbutton_var2, onvalue=1, offvalue=0,height=2, width=10)
        checkbutton2.grid(column=1, row=1)
        button = Button(self.master, text="push", bg="pink", bd=100, fg="white",
                    command=lambda: self.retrieve_input(user_input.get(), self.checkbutton_var1.get(), self.checkbutton_var2.get()))
        button.grid(column=0, row=3, padx=20, pady=20, sticky="NEWS")


    def retrieve_input(self, p, *args):
        self.path = p
        #print(self.path)
        for el in args:
            self.type.append(el)
            #print(self.type)

def main():
    tk = Tk()
    app = CreateGUI(tk)
    app.add_labels()
    user_input = app.add_entries()
    app.add_buttons(user_input)
    print(app.type)
    print(app.path)
    tk.mainloop()

When I start the program, write the input and press the button, it does not print anything. There are empty brackets printed the moment the program is initiated. The prints inside the retrieve_input are printing exactly what I need, but I need this inputs outside of the class, because they will be an input to another class.

I tried everything related to this problem, but it is not working and I would really appriciate any kind of help. Thanks!

You are getting the input for the Entry widget right before anyone can have a chance to type in it. As a result, user_input.get() will return an empty string. One thing you can do is make some sort of trigger for calling add_buttons() that the user activates when they are done filling out user_input. Further tweaking after that should make it work.

Please tell me if you have any more trouble.
