...print function using this new dict.
Something like :
def myprint(d):
for k, v in d.items():

Is there a short contains function for lists?
...erse operator:
if myItem not in list:
# do something
It's work fine for lists, tuples, sets and dicts (check keys).

Why does [5,6,8,7][1,2] = 8 in JavaScript?
...nd box i.e. [1,2,3] becomes [3] i.e. the last item so the result will be 4
for example if you keep [1,2,3,4,5,6] in an array
var arr=[1,2,3,4,5,6];
arr[3]; // as [1,2,3] in the place of index is equal to [3]
similarly
*var arr2=[1,2,3,4,5,6];
// arr[1,2] or arr[2] will give 3*
But when yo...
How do I add multiple arguments to my custom template filter in a django template?

Calculate distance between two points in google maps V3
...
If you want to calculate it yourself, then you can use the Haversine formula:
var rad = function(x) {
return x * Math.PI / 180;
};
var getDistance = function(p1, p2) {
var R = 6378137; // Earth’s mean radius in meter
var dLat = rad(p2.lat() - p1.lat());
var dLong = rad(p2.lng() - p...

It is unfortunately not supported in older versions of MSTest. Apparently there is an extensibility model and you can implement it yourself. Another option would be to use data-driven tests.
