thanks lawrence...however this func doesnt return the permuted strings, so
i added some code as follows to generate a list of all the permutations:
def permute(seq):
l = []
if len(seq) == 0:
yield []
else:
for i in range(0,len(seq)):
for rest in permute(seq[:i] + seq[i+1:]):
yield (seq[i],) + rest
for t in permute(seq):
l.append(''.join(t))
return l
This gives me a syntax error!
I need to output a list that has all the permutations of the input string.
