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.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
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!

Posts may use any of the Perl Monks Approved HTML tags. Currently these include the following:
<code> <a> <b> <big>
<blockquote> <br /> <dd>
<dl> <dt> <em> <font>
<h1> <h2> <h3> <h4>
<h5> <h6> <hr /> <i>
<li> <nbsp> <ol> <p>
<small> <strike> <strong>
<sub> <sup> <table>
<td> <th> <tr> <tt>
<u> <ul>
-
Snippets of code should be wrapped in
<code> tags not
<pre> tags. In fact, <pre>
tags should generally be avoided. If they must
be used, extreme care should be
taken to ensure that their contents do not
have long lines (<70 chars), in order to prevent
horizontal scrolling (and possible janitor
intervention).
