Hi Michael,
Is a non regex way any help? I can think of a way that uses string methods -
space=" "
stringStuff="Stuff with multiple spaces"
indexN = 0
ranges=[]
while 1:
try:
indexN=stringStuff.index(space, indexN)
if indexN+1 == space:
indexT = indexN
while 1:
indexT += 1
if not indexT == " ":
ranges.append((indexN, indexT))
break
indexN=indexT +1
else:
indexN += 1
except ValueError:
ranges.reverse()
for (low, high) in ranges:
stringStuff.replace[stringStuff[low:high], space]
HTH

'There is only one basic human right, and that is to do as you damn well please.
And with it comes the only basic human duty, to take the consequences.
