Display different frames based on logged in value in tkinter - python-3.x

Question

I am creating an office management application. In this, there is admin and staff. In the Log In page based on whether it is admin or staff different frames needs to be displayed.
I used an if-else statement for this purpose.I tried to compare the value of username using get() but was unable to print its value inside the function.
Following is the code I executed.

cursor_variable = employee.cursor()
cursor_variable.execute("INSERT INTO login VALUES ('" + self.u_name + "','" + self.p_word + "')")
employee.commit()
employee.close()
I have no errors. Whether it's admin or staff the else condition works and staff page is getting displayed.
Any help is highly appreciated.

I modified the class LogIn(BasePage) as follows and it works. I changed the submit(self) to submit(self,controller).
Thank you everyone for your response.
