python - Is there a command choose where you want to start and stop parsing data in a text file? -


is there command (line or string) choose want start , stop parsing data of x in text file? there sort of string command read between specific parts of strings?

let's textfile is:

[6-1-14] data record [9:55:00am] [6-1-14]   x=4, y=5 [9:55:00am] [6-1-14]   x=3, y=4 [9:55:00am] [6-1-14] data stop [9:55:00am] [6-1-14] debug: start [9:55:00am] [6-1-14]   x=4, y=5 [9:55:00am] [6-1-14] debug: end [9:55:00am] [6-2-14] data record [9:55:00am] [6-2-14]   x=2, y=3 [9:55:00am] [6-2-14]   x=1, y=2 [9:55:00am] [6-2-14] data stop [9:55:00am] [6-3-14] data record [9:55:00am] [6-3-14]   x=0, y=1 [9:55:00am] [6-3-14] data stop [9:55:00am]

desired output: all values stored in list between data record , data stop. values between debug: start , debug: end should not recorded.

x =[4,3,2,1]

motive code: store values of x between strings data record , data stop , else.

assuming using python can like:

text = """  text above """ p1=0 output="" while true:     p2 = text.find("data record",p1)+11     p3 = text.find("data stop", p1)     if p2<0 or p3<0: break     s = text[p2:p3]     output +=s     p1=p3+10  print output

which prints

[9:55:00am] [6-1-14]   x=4, y=5 [9:55:00am] [6-1-14]   x=3, y=4 [9:55:00am] [6-1-14]  [9:55:00am] [6-2-14]   x=2, y=3 [9:55:00am] [6-2-14]   x=1, y=2 [9:55:00am] [6-2-14]  [9:55:00am] [6-3-14]   x=0, y=1 [9:55:00am] [6-3-14]

which bit between record , stop bits. parse that?

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
