[Tutor] what is the difference

[Michael H. Goldwasser]

Hi John,

It depends upon whether the "..." code fragment is affected in any way
by the value of self._inFlush.  The first code sample you offer should
be identical to the following.

    if not self._inFlush:
    	self._inFlush = True    # reset this before the ...
    	...
    else:
    	return

With regard,
Michael
