# There's a list of default generators which is quit handy if needed. Lets # take a brief look on them. ## range - generate q sequential list of integers result = range(0, 10, 2) # from, to, step print "range(0, 10, 2): ", repr(result) for i in range(0, 10): print i, print ## xrange - create generator of sequential integers result = xrange(0, 10, 2) # from, to, step print "xrange(0, 10, 2): ", repr(result) for i in xrange(0, 10): print i, print ## enumerate - create a list of pairs baised on given sequence letters = "abcdefg" for index, letter in enumerate(letters, 1): print "#{0}:{1}; ".format(index, letter), print
