I think there is a slight problem to view above code with mozilla, that the reason confused me. Now I checked the code with Internet Explorer, that works fine.

The viewing problem happens to the following code:
—-
for i in range(setsize):
rlength = random.randint(minlength, maxlength)
sequenceset.append(simulate_sequence(rlength))
—-
With mozilla, it shows:
—
for i in range(setsize):
rlength = random.randint(minlength, maxlength)
sequenceset.append(simulate_sequence(rlength))
—

Thanks!

In fact this script generates only one set of sequences. It was never intended to generate more than one set. The difference to the previous entry is that it can generate sequences with different lengths.

Sorry if the explanation wasn’t clearer. I will write a post and incorporate your ideas.

No matter how I change the value of ‘setsize’, the above script always produces 1 set of sequence, that is supposed to produce the different sets of random sequences according to the changes of ‘setsize’.

I have done a bit modification with above script after line 17, that works fine now. Please have a look and jive some suggestions.

rlength = []

for i in range(setsize):
rlength.append(random.randint(minlength, maxlength))

for length in rlength:
sequenceset.append(simulate_sequence(length))

for sequence in sequenceset:
print sequence
