Don't forget grep!
my @True;
for my $Element (@Array){
if ($Element){
push @True, $Element;
}
}
becomes:
my @True = grep {$_} @Array;
To get every nth element from a list:
(Previously posted by me as Anonymous Monk...)
#(For every fourth element in @List)
grep {not ++$i % 4} @List;
#(To skip every fifth element)
grep {++$i % 5} (1..50)
I suppose we could argue that grep isn't really
intended as a looping mechanism, but map seems to be popular
around here, and map is implemented on grep code (internally)
so...

Are you posting in the right place? Check out Where do I post X? to know for sure.

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).

or How to display code and escape characters
are good places to start.
