python - iterating over a list by a certain number -


this question has answer here:

suppose have following list:

['id-1213fsr53', 'waiting', '54-81-24-40', 'world', 'id-343252sfsg', 'waiting', '54-41-06-143', 'hello']

the list can subdivided tuples in following format:

(id, status, ip-address, name)

so, in other check status, need iterate on list 4 element tuples, like:

for s in status:    (id, status, ip-address, name) = s # (s 4 element list)    # increment s 4, , continue loop

how can achieve such behavior in python?

using method of grouping elements groups zip() docs:

data = ['id-1213fsr53', 'waiting', '54-81-24-40', 'world', 'id-343252sfsg', 'waiting', '54-41-06-143', 'hello'] s in zip(*[iter(data)]*4):     (id, status, ip_address, name) = s

you can perform unpacking in iteration:

for id, status, ip_address, name in zip(*[iter(data)]*4):     #

here zip() call doing allows type of iteration:

>>> zip(*[iter(data)]*4) [('id-1213fsr53', 'waiting', '54-81-24-40', 'world'), ('id-343252sfsg', 'waiting', '54-41-06-143', 'hello')]

css - Make div keyboard-scrollable in jQuery Mobile? -

from can tell, although jquery-mobile-powered pages can contain divs overflow set scroll or auto, , these divs can scrolled one-screen bar or mouse wheel, cannot scrolled using arrow keys, page-up/page-down, or home/end. instead, official "page" div (with data-role="page") absorbs input. perhaps other divs can't acquire focus, i'm not sure. is there way around this? edit: jsfiddle of simple example: https://jsfiddle.net/qogz0shx/ <script src="https://ajax.googleapis.com/ajax/libs/jquery/2.1.4/jquery.min.js"></script> <script src="https://ajax.googleapis.com/ajax/libs/jquerymobile/1.4.5/jquery.mobile.min.js"> </script> <link rel="stylesheet" href="https://code.jquery.com/mobile/1.4.5/jquery.mobile-1.4.5.css"/> <style> #outer { overflow:scroll; height: 50vh; width: 50vw; } #inner { height: 500vh; width: 500vw; } ...
