column names: name , reading , channel , time i'm trying find max value each distinct name . each name has many values read on time interval of once every hour. goal pick out max value each distinct name , record time interval occurred in. so far have gotten code: select name, max(reading) "max_reading", data, channel, time interval_data group name, data, channel however, gives me error saying time has aggregated or grouped by. there easy way append time max value occurred @ output , not have perform grouped by/aggregate function on column? sample data: name reading data channel time 1 1 1 1 1/15/2015 09:00 1 3 1 1 1/15/2015 10:00 1 2 1 1 1/15/2015 11:00 1 5 1 1 1/15/2015 12:00 2 2 1 1 1/15/2015 09:00 2 4 1 1 1/15/2015 10:00 2 6

when use requesthandler.get_argument() , requesthandler.get_query_argument() , requesthandler.get_body_argument() ? what use-case each of them? also request.body , request.argument in these cases? used in scenarios? and, there request.query or similar too? most http requests store parameters (say, form values) in 1 of 2 places: url (in form of ?foo=bar&spam=eggs query string ), or in request body (when using post request , either application/x-www-form-urlencoded or multipart/form-data mime type ). the request.get_query_argument() looks url parameters, requesthandler.get_body_argument() lets retrieve parameters set in post body. requesthandler.get_argument() method retrieves either body or url parameter (in order). you use request.get_argument() when explicitly don't care parameter comes , endpoint supports both , post parameters. otherwise, use 1 of other methods, keep explicit parameters come from. the request.get_*_argument methods use r

this question has answer here: select specific element before other element 5 answers i have situation: the transition on entering is, after 1sec delay, fade-in 100% opacity: transition: opacity 1s ease 1s; the transition on leaving is, within 1sec fade out 0% opacity: transition: opacity 1s; the .leaving element removed after 1second. after removed want position:static on .entering so in other words: "when .entering not followed .leaving, apply position:static" , "when .entering followed .leaving should position:absolute" i'm trying this .entering { position: absolute; } .entering:not(+ .leaving) { position: static; } however not working. ideas? let's example in simplified case, background colors. if .entering followed .leaving , it's background color should red. if .entering followed non- .leaving (or f

i take large file in python 2.7: 123 456 gthgggth 223 567 fgrthsys 12933 4656832 gjwsoooskkssj ..... and want read in file line line, disregard third element, , subtract second element in each line first element. line 1 above return 333. i have tried far: def deletelast(list): newl = list.pop() return newl f = open(file_name, 'r') line = f.readline() while line: l = line.split() l2 = deletelast(l) l3 = [int(number) number in l2] length = l3[1]-l3[0] print length f.close() but, when try compiler says: valueerror: invalid literal int() base 10: 't' all appreciated. that because list.pop() returning "popped off" item, doesn't return list again. instead of deletelast function have written, better use slice this: l2 = line.split()[0:2] you going run problem later because while loop isn't advancing @ all. consider using loop instead.
