python - How to update session object -

-

with 2 <a>:

<a id="100" onclick="createtriggered(this.id)"<i></i> click link </a> <a id="200" onclick="createtriggered(this.id)"<i></i> click link </a>

both linked same onclick javascript function:

<script type=text/javascript>   $script_root = {{ request.script_root|tojson|safe }};   function onclick(id){       var data = $.getjson($script_root + '/triggered', {a:id} );       window.alert({{ "session.keys()" }});   } </script>

this javascript function takes clicked <a> id , sends flask function:

@app.route('/onclick') def onclick():     session['a_id'] = request.args.get('a')     return ('ok')

after flask function gets id updates session object creating new key session['a_id'].

finally javascript window.alert used check if session object has new 'a_id' key should set flask function. when window.alert pops shows new key missing. refreshing page , re-clicking <a> link pop window.alert() again time showing new session['a_id'] key there. looks update of session object lagging behind. have refresh page in order browser pick change made flask function. there way assure update made flask function session object reflected immediately? finally, since updating session object global entire session don't want return template or redirect link. want flask function set session variables used somewhere down logic. ok return dummy string flask function in case?

arrays - Algorithm to find ideal starting spot in a circle -

-
so problem have been debating such: your given array of integers representing circle. then, have pick spot in circle start. place start, compare value @ array number of steps took there , if steps less or equal number, include in final set. find place start have elements in set. ex, a=[0, 1, 2] if start @ index=0, then: a[0]=0 < =0 0 included a[1]=1 < =1 1 included a[2]=2 < =2 2 included final set: {0,1,2} if start @ index=1, then: a[1]=1 > 0 1 not included a[2]=2 > 1 2 not included here loop around a[0]=0 > 2 0 included final set: {0} if start @ index=2, then: a[2]=2 > 0 2 not included, here loop around a[0]=0 < = 1 0 included a[1]=1 < = 2 1 included final set: {0,1} so in trivial case, starting position index=0 best position results in final set elements. brute force method of finding obvious, trying find more efficient method. attempts far have been examine trying find max intersect of viable starting ranges calculated each element in arr...
