When trying to use the .config() method to change the font size of the 'button1' attribute of the 'studentmainmenuscreen' object I got this error:
Error

I can't figure out why this error is occurring! Please help me?!

You're changing the type of object in line:

self.button1 = Button(self.canvas, text=b1t, command=b1c, font=('Arial', 30), relief='flat').place(x=b1x,y=b1y)

For both buttons.

You can create the button first, then call the place() methods:

self.button1 = Button(params)
self.button2 = Button(params)
self.button1.place(params)
self.button2.place(params)

Here is a good article to refer to.
