Python print nth element from list of lists -


this question has answer here:

i have following list:

[[50.954818803035948, 55.49664787231189, 8007927.0, 0.0],  [50.630482185654436, 55.133473852776916, 8547795.0, 0.0], [51.32738085400576, 55.118344981379266, 6600841.0, 0.0],  [49.425931642638567, 55.312890225131163, 7400096.0, 0.0],  [48.593467836476407, 55.073137270550006, 6001334.0, 0.0]]

i want print third element every list. desired result is:

8007927.0 8547795.0 6600841.0 7400096.0 6001334.0

i tried:

print data[:][2]

but not outputting desired result.

many way this. here's simple list way, without explict loop.

tt = [[50.954818803035948, 55.49664787231189, 8007927.0, 0.0], [50.630482185654436, 55.133473852776916, 8547795.0, 0.0], [51.32738085400576, 55.118344981379266, 6600841.0, 0.0], [49.425931642638567, 55.312890225131163, 7400096.0, 0.0], [48.593467836476407, 55.073137270550006, 6001334.0, 0.0]]  print [x[2] x in tt]  > [8007927.0, 8547795.0, 6600841.0, 7400096.0, 6001334.0]

and making safe potentially shorted lists

print [x[2] x in tt if len(tt) > 3]

more sophisticated output (python 2.7), prints values newline (\n) seperated

print '\n'.join([str(x[2]) x in tt])  > 8007927.0 > 8547795.0 > 6600841.0 > 7400096.0 > 6001334.0

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
