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)]

krsortSort an array by key in reverse order


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.



The input array.


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

Return Values

Example #1 krsort() example

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

The above example will output:

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