hi Harry,
thanks for sharing this. It turns out to be very helpful. Unfortunately sometimes I get into trouble when your code pop from an empty list (see below).
This is my proposal for a fix but there might be a more clever alternative...
def next (prevList):
sum = 0.0
retval = ""
index = random.random ()
# Shorten prevList until it's in mapping
while toHash (prevList) not in mapping:
if prevList:
prevList.pop (0) # cant pop from empty list
else:
curr = random.choice (starts)
sent = curr.capitalize ()
prevList = [curr]
# Get a random word from the mapping, given prevList
for k, v in mapping [toHash (prevList)].iteritems ():
sum += v
if sum >= index and retval == "":
retval = k
return retval
all the best,
Mark
