How to calculate the frequency of a list of symbols in Python -


i trying calculate frequency of amount of times each symbol shown in list. far have code doesn't seem work correctly because shows error message below...

uniques = set(words.split()) attributeerror: 'tuple' object has no attribute 'split'

this code far... 

def calculate_frequency():         words = ()         uniques = set(words.split())         freqs = [(item, words.split.count(item)) item in uniques]         print(freqs)

the symbols want know frequency of , stored in variable 'words' shown below...

for frequency counts, use collections.counter(), , feed whole text; can remove newlines splitting , rejoining.

i'm assuming words global string newlines it; split on newlines str.splitlines():

from collections import counter  def calculate_frequency():     freqs = counter(''.join(words.splitlines()))     symbol, count in freqs.most_common():         print symbol, count

this produces frequency list sorted common least common symbol.

demo:

>>> collections import counter >>> words = '''\ ... #+/084&" ... #3*#%#+ ... 8%203: ... ,1$& ... !-*% ... .#7&33& ... #*#71% ... &-&641'2 ... #))85 ... 9&330* ... ''' >>> def calculate_frequency(): ...     freqs = counter(''.join(words.splitlines())) ...     symbol, count in freqs.most_common(): ...         print symbol, count ...  >>> calculate_frequency() # 8 & 7 3 6 % 4 * 4 1 3 0 3 8 3 ) 2 + 2 - 2 2 2 4 2 7 2 ! 1 " 1 $ 1 ' 1 , 1 / 1 . 1 5 1 6 1 9 1 : 1

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
