Sort a JSON using Python -


i trying ot sort json object using python.

i have following object : 

{    "text": "hello world",   "predictions":     [      {"class": "class 1", "percentage": 4.63},      {"class": "class 2", "percentage": 74.68},      {"class": "class 3", "percentage": 9.38},      {"class": "class 4", "percentage": 5.78},      {"class": "class 5", "percentage": 5.53}    ] }

and want have object instead : 

{    "text": "hello world",   "predictions":     [      {"class": "class 2", "percentage": 74.68},      {"class": "class 3", "percentage": 9.38},      {"class": "class 4", "percentage": 5.78},      {"class": "class 5", "percentage": 5.53},      {"class": "class 1", "percentage": 4.63}    ] }

in fact, want order array of objects percentage.

i have tried command : 

sorted_obj = sorted(json_obj['predictions'], key=lambda k: k['percentage'], reverse=true)

and had error :

traceback (most recent call last):   file "<stdin>", line 1, in <module> typeerror: string indices must integers

any needed,

thanks

you can use sorted sort values, :

json_obj = {    "text": "hello world",   "predictions":     [      {"class": "class 1", "percentage": 4.63},      {"class": "class 2", "percentage": 74.68},      {"class": "class 3", "percentage": 9.38},      {"class": "class 4", "percentage": 5.78},      {"class": "class 5", "percentage": 5.53}    ] }  sorted_obj = dict(json_obj)  sorted_obj['predictions'] = sorted(json_obj['predictions'], key=lambda x : x['percentage'], reverse=true)  print(sorted_obj) print(json_obj)

this result in :

# sorted values based on 'predictions' -> 'percentage' {'predictions': [{'percentage': 74.68, 'class': 'class 2'}, {'percentage': 9.38, 'class': 'class 3'}, {'percentage': 5.78, 'class': 'class 4'}, {'percentage': 5.53, 'class': 'class 5'}, {'percentage': 4.63, 'class': 'class 1'}], 'text': 'hello world'}  # original json_obj remain unchanged have created new object sorted_obj values of json_obj using dict() {'text': 'hello world', 'predictions': [{'class': 'class 1', 'percentage': 4.63}, {'class': 'class 2', 'percentage': 74.68}, {'class': 'class 3', 'percentage': 9.38}, {'class': 'class 4', 'percentage': 5.78}, {'class': 'class 5', 'percentage': 5.53}]}

commonjs - How to write a typescript definition file for a node module that exports a function? -

consider, toml node module can use: // toml.d.ts declare module toml { export function parse(value:string):any; } declare module "toml" { export = toml; } then: /// <reference path="../../../../../defs/toml/toml.d.ts"/> import toml = require('toml'); toml.parse(...); however, node module export single function, such 'glob' ( https://github.com/isaacs/node-glob ). the node usage of module be: var glob = require("glob") glob("*.js", {}, callback(err, files) { ... }); you'd naively expect this: // glob.d.ts declare function globs(paths:string, options:any, callback:{(err:any, files:string[]):void; ...but because typescripts 'import' semantics bit strange, seems can use 'import .. = require()' statement alias modules . trying call: /// <reference path="../../../../../defs/glob/glob.d.ts"/> import blog = require('glob'); results in: error ts2072: mod

thorough guide for profiling racket code -

did googling ("racket profiling", "racket measure performance"), didn't find , there no examples in docs. did google "profile" search on htdp - no luck. (profile (f ...)) output isn't obvious other small snippets. ideally want python's python -m cprofile usage examples. when search "python profiling", both duckduckgo , google give top result: 26.4. python profilers . (although scanned quickly, seems more of reference "thorough usage guide" examples. if had else in mind, perhaps please link that?) the equivalent racket documentation be: profile: statistical profiler . a usage example: #lang racket (require profile) (profile-thunk (thunk (function-to-profile arg0 arg1) )) here (thunk e) convenience (lambda () e) . bigger example: #lang racket (module mod racket (provide f) (define (f) (for/list ([i 10000]) i))) (require (prefix-in mod: 'mod)) (define (f) (for ([i 10000
