counter

I'm trying to make a dropdown menu using nested <ul> , every <li> displaying a number generated with CSS Counters. Sub-menus are hidden with display:none when not hovered. My problem is that counters are not incremented when an element has display set to none . Do you know a CSS property to prevent this? If I replace display: none by visibility: hidden , it's working but I'm not sure if it's nice to use this for my menu, are there any traps? Harry You can mimick the display: none (hidden) behavior by setting the font-size to 0px and this would make the element be counted by the counter

I'm trying to decrement the counter of a for loop as the loop is running. Unfortunately, Lua doesn't seem to allow that. This piece of code should run forever: for i = 1, 100 do print (i) i = i - 1 end but it does, in fact, simply print the series 1-100. Is that by design? If so, how do I decrement the counter of a running loop (for example because the current cycle was disqualified and should run again)? It's by design. From Lua reference manual : 3.3.5 – For Statement All three control expressions are evaluated only once, before the loop starts. They must all result in numbers. So modifying

I have a list of lists in python and I need to find how many times each sub-list has occurred. Here is a sample, from collections import Counter list1 = [[ 1., 4., 2.5], [ 1., 2.66666667, 1.33333333], [ 1., 2., 2.], [ 1., 2.66666667, 1.33333333], [ 1., 4., 2.5], [ 1., 2.66666667, 1.33333333]] c = Counter(x for x in iter(list1)) print c I above code will work, if the elements of the list were hashable (say int), but in this case they are lists and I get an error TypeError: unhashable type: 'list' How can I count these lists so I get something like [ 1., 2.66666667, 1.33333333], 3 [ 1., 4., 2.5]

I have general data, e.g. strings: np.random.seed(343) arr = np.sort(np.random.randint(5, size=(10, 10)), axis=1).astype(str) print (arr) [['0' '1' '1' '2' '2' '3' '3' '4' '4' '4'] ['1' '2' '2' '2' '3' '3' '3' '4' '4' '4'] ['0' '2' '2' '2' '2' '3' '3' '4' '4' '4'] ['0' '1' '2' '2' '3' '3' '3' '4' '4' '4'] ['0' '1' '1' '1' '2' '2' '2' '2' '4' '4'] ['0' '0' '1' '1' '2' '3' '3' '3' '4' '4'] ['0' '0' '2' '2' '2' '2' '2' '2' '3' '4'] ['0' '0' '1' '1' '1' '2' '2' '2' '3' '3'] ['0' '1' '1' '2' '2' '2' '3' '4' '4' '4'] ['0' '1' '1' '2' '2' '2' '2' '2' '4' '4']] I need count with reset if difference

Looking for a script that I can ideally enter a starting number and a start date, which then continues to increment based on a rate I set e.g. 1 per second . The script would ideally calculate what number it should be on based on the difference between the current time and start time. It's meant to look like it's showing a live count. Ideally, something like the counter on http://sendgrid.com/ Has anyone got a link or plugin or solution they can share? If the numbers can be replaced with images of numbers even better, but a starting point would be much appreciated. Thanks If you want a
