is there built-in reducebykey functionality in python? if not, how can imitate functionality? for example, if i'm doing simple word count: >>> x=[('a', 1), ('a', 1), ('b', 1), ('c', 1)] >>> reduce(lambda a,b:a+b, x) ('a', 1, 'a', 1, 'b', 1, 'c', 1) what wanted have return [('a',2), ('b',1), ('c',1)]. reduce() function ended iterating through tuples together, , didn't combine keys. way around this? you can use ordereddict . preserve order also. from collections import ordereddict result = ordereddict() item in x: result[item[0]] = result.get(item[0], 0) + item[1] result [('a', 2), ('b', 1), ('c', 1)] here, iterating on dictionary. key item[0] in result ordereddict. if found, add item[1] 1 in our case value present there. else, take default value 0 , add item[1] (this happen when element encountered first time). ...

i writing small game using bootstrap , want font size remain proportionally consistent on phone, tablet , pc. <h1>points: {{points}}</h1> the trouble above smaller on higher level resolutions , wrecks layout have designed game. how solve issue? as suggested @ckuijjer, vw unit works well. resize window, font size resized in proportion size of window. @media { h1 { font-size: 6vw;} h2 { font-size: 5vw;} h3 { font-size: 4vw;} h4 { font-size: 3vw;} h5 { font-size: 2vw;} h6 { font-size: 1vw;} }

i trying make app reads data device on btle , displays data in streaming graph. want use of polymer. nice shield complexity of btle. have html tag btle displays btle icon , double click connect device. ones connected want (notify)data connect graph. when @ examples of polymer data binding binds slow data sources input field. question can done (2kb/sec) polymer or slow , should keep data out of polymer ? performance of data-binding has how many bindings there are, , expense of whatever side-effects trigger, not data-size or transfer speeds. generally measured in seconds slower kind of throughput worry in polymer.

if create bool within class, bool check , defaults false. when create same bool within method, bool check (instead of within class), error "use of unassigned local variable check". why? yuval , david's answers correct; summing up: use of unassigned local variable bug, , can detected compiler @ low cost. use of unassigned field or array element less bug, , harder detect condition in compiler. therefore compiler makes no attempt detect use of uninitialized variable fields, , instead relies upon initialization default value in order make program behavior deterministic. a commenter david's answer asks why impossible detect use of unassigned field via static analysis; point want expand upon in answer. first off, variable, local or otherwise, in practice impossible determine exactly whether variable assigned or unassigned. consider: bool x; if (m()) x = true; console.writeline(x); the question "is x assigned?" equivalent "does m()...
