Python replacement for PHP's ksort [ 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 key order.
def ksort(d):
     return [(k,d[k]) for k in sorted(d.keys())]

PHP ksort

Examples

Example #1 ksort() example

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

The above example will output:

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