[Python] Can't use get() when trying to pull value from Entry() widget - Tkinter

password = ''.join(random.choice(characters) for _ in range(length))
return password

root = Tk()
root.title("PASSWORD GENERATOR")
root.geometry("450x400")
int_ans_var = IntVar()
title = Label(root, text="RoosSec Password Generator", font=("bold", 16), fg = "Black", bg="#228B22").pack()
input_num = Label(root, text="Password length: ", font=("bold", 12), fg = "Black", bg="#228B22").place(x=100, y=150)
num_box = Entry(root, font=("bold", 14), width=10, fg= "Black", bg="White", justify=LEFT).place(x=230, y=150)
int_ans_var = num_box.get()
btn = Button(root, text="Generate Password", fg="white", bg="black", height="2", width="15", command=generate_password).place(x=300, y=350)
root.mainloop()
