Python replacement for PHP's krsort [ edit | history ]
In Python, a dictionary (i.e. associative array) is not ordered, so it is not possible to "modify the order" of the dictionary like you can in PHP. Instead, we return a new list of the (key, value) pairs of the dictionary sorted in reverse key order.
def ksort(d):
     return [(k,d[k]) for k in sorted(d.keys(), reverse=True)]

(PHP 4, PHP 5)

krsortSort an array by key in reverse order

Description

bool krsort ( array &$array [, int $sort_flags= SORT_REGULAR ] )

Sorts an array by key in reverse order, maintaining key to data correlations. This is useful mainly for associative arrays.

Parameters

array

The input array.

sort_flags

You may modify the behavior of the sort using the optional parameter sort_flags , for details see sort().

Return Values

Returns TRUE on success or FALSE on failure.

Examples

Example #1 krsort() example

<?php
$fruits 
= array("d"=>"lemon""a"=>"orange""b"=>"banana""c"=>"apple");
krsort($fruits);
foreach (
$fruits as $key => $val) {
    echo 
"$key = $val\n";
}
?>

The above example will output:

d = lemon
c = apple
b = banana
a = orange
