I think:
class Stack:
def __init__( self, *args ):
self.data = args
def __str__( self ):
return f"Stack({','.join(str(x) for x in self.data)})"
gives equivalent output for the if len(args) is 0 or 2, if it’s okay for
self.data to be a tuple.
class Stack:
def __init_

There is no tkinter package on PyPI. It's part of the standard library
and included with the python.org installer as an optional component.
