Hello,
I just wrote a short script that generates look and say sequence. What
do you Python guys think of it? Too "Java-ish"? I can't shake off the
feeling that somebody may have done this with 2-3 lines of Python
magic. Heh.
# generator for sequence
def lookAndSaySequence(firstTerm, n):
term = str(firstTerm)
for i in xrange(n):
yield term
term = lookAndSay(term)
# the method that looks, and says
def lookAndSay(number):
look_at_this = str(number)
say_this = ['0', look_at_this[0]]
for digit in look_at_this:
if say_this[-1] != digit:
say_this.extend(('1', digit))
else:
say_this[-2] = str(int(say_this[-2]) + 1)
return "".join(say_this)
# run it!
print [x for x in lookAndSaySequence(1, 30)]
Thanks,
Ray
