i have sql script works on mysql (up current versions). built copy of mariadb-10.2.8 source on linux machine , got database , running. however, sql script fails, because mariadb returning null unhex() call, shouldn't. the call producing 20-byte random binary string in particular format (it's bittorrent node id). concatenate required bytes random bytes, bytes being limited particular range of values. these constructed 40-character hex string, run through unhex(). the sql is: unhex( concat( '414c2', hex( 8 + round( rand() * 7 ) ), substr( sha( uuid( ) ), 6, 33 ), hex( 2 + round( rand( ) ) * 8 ) ) ) if take off unhex() function, 40-character hex string: mariadb [bt]> select concat('414c2', hex(8+round(rand()*7)),substr(sha(uuid()),6,33),hex(2+round(rand())*8)); +-----------------------------------------------------------------------------------------+ | concat('414c2', hex(8+round(rand()*7))

salary_data list in python.when used enumerate function in loop below,everything went well. ##salary_data = enumerate(salary_data) max_label = [i i,x in enumerate(salary_data) if x==max(salary_data)] print max_label but when use enumerate function below,i got salary_data empty list,and valueerror: max() arg empty sequence.i don't know why. salary_data = enumerate(salary_data) max_label = [i i,x in salary_data if x==max(salary_data)] print max_label enumerate(salary_data) iterator because wrapped in enumerate . means exhausted (empty) when call max on (besides giving wrong maximum). you should calculate max front (avoiding recalculation) , iterate on enumerate d data: max_ = max(salary_data) # avoids repeated maximum calculation in loop salary_data_enumerated = enumerate(salary_data) # other variable name, readability max_label = [i i, x in salary_data_enumerated if x==max_]

i had asked previous question regarding multiple bootstrap carousels , had received absolutely fine code stack overflow user. you can see code here: how place 2 bootstrap carousels in same page? under last edit i using same code provided user. problem carousels freezing when page stays open long. by freezing mean first slider, stops sliding after specified interval. if manually click on navigation button, slides. for second carousel , thumbnails, problem when clicking on thumbnail, respective image not showing in second carousel. no amount of refreshing or copy pasting code page helps. there other elements on page too, none have jquery or similar class names. overlapping of class names or id names ruled out. where problem? any kind of appreciated. thanks. here you're missing }); in code, review jsfiddle, terminator jquery(document).ready(function($) { . check jsfiddle here .
