perlquestion xiaoyafeng Hi gurus, I have big trouble!Last day, a python fan have claimed perl is a garbage language.python is much better than it. And raise a question to test perl's "ability": using letters of a string,enumerate all secret code. below is my code(I admit it's a garbage) <code> $letters = shift @ARGV ||"ABC"; @letter = split //,$letters; for $a (1..$#letter) { for $b (1..$#letter) { for $c (1..$#letter) { $scode = $letter[$c].$letter[$b].$letter[$a]; print $scode."\n"; } } } </code> below is his code (with python) <code> import string DEFAULT_CHAR_SET = string.letters + string.digits + string.punctuation class PasswordGenerator(object) : def __init__(self, seeds = DEFAULT_CHAR_SET) : self.seeds = seeds self.Outer = None self.cursor = 0 def next(self) : self.cursor += 1 if self.cursor == len(self.seeds) : self.cursor = 0 if not self.Outer : self.Outer = PasswordGenerator(self.seeds) else : self.Outer.next() def value(self) : if self.Outer : return self.Outer.value() + self.seeds[self.cursor] else : return self.seeds[self.cursor] def __iter__(self) : while 1 : yield self.value() self.next() if __name__ == "__main__" : g = PasswordGenerator() for i in g : print i </code> I'm a perl fan and zealot,but not a accomplished programmer.So my question is: 1.Who can transfer his code to perl, or tell me algorithm of his code? I don't know python at all! 2.We could write a better code with perl,couldn't we? Thanks in advance for answer my foolish and childish question! All responds are appreciated!
