Oh - and while we are at it - how about having merge_list() and unique_list()
as part of the core too??
def unique_list(seq): # Dave Kirby
# Order preserving
seen = set()
return [x for x in seq if x not in seen and not seen.add(x)]
def merge_list(seq):
merged = []
for s in seq:
for x in s:
merged.append(x)
return merged
Raymond - any thoughts on these 3 requests???
Cal
