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)

$letters = shift @ARGV ||"ABC";
@letter = split //,$letters;
for $a (1..$#letter) {
       for $b (1..$#letter) {
               for $c (1..$#letter) {
                          $scode = $letter[$c].$letter[$b].$letter[$a]
+;
print $scode."\n";
}
}
}

below is his code (with python)

import   string  
   
  DEFAULT_CHAR_SET     =   string.letters   +   string.digits   +   st
+ring.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(s
+elf.seeds)  
                          else   :  
                                  self.Outer.next()  
          def   value(self)   :  
                  if   self.Outer   :

                          return   self.seeds[self.cursor]  
          def   __iter__(self)   :  
                  while   1   :

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!
