[Tkinter] Programmatically creating buttons that remember their positions

[Gribouillis]

did my first code create one lambda that was referenced by all buttons, or did it crate a lambda for each function that all referenced the same variables?

It created a lambda for each button that all referenced to the same variables as in this example

>>> def func():                                                                             
...     var = 3                               
...     spam = lambda: var        
...     var = 4                               
...     ham = lambda: var                                                                   
...     return spam, ham                                                                    
...                                                                                         
>>> f, g = func()
>>> f is g
False
>>> f.__closure__
(<cell at 0x7f3135163160: int object at 0x7f3135374150>,)
>>> g.__closure__
(<cell at 0x7f3135163160: int object at 0x7f3135374150>,)
>>> f.__closure__[0].cell_contents             
4
>>> g.__closure__[0].cell_contents             
4
>>>
