There's no good way to change the variable space programmatically.
Python has more flexibility than most other languages as it is.
Anyway, your best bet is to use an independent namespace:

class Globals: pass
setattr( Globals, 'itemX', 'value1' )
setattr( Globals, 'itemX', 'value2' )

Your 'updateCheck' function would then have to take the namespace as
an additional parameter.
