regex - python re.match list of regular expressions -


i have 2 lists: ignorelist list of regular expressions, , list calledurllist. trying make if index item in urllist matches regular expression in ignorelist, not added finallist

ignorelist = ['(?:\.)amazon\.com(?:\/(?:.*))',             '(?:\.)google\.com(?:\/(?:.*))']  urllist = ['api.amazon.com/', 'fakedomain.com/'] finallist = []  r in ignorelist:     r = re.compile(r)     finallist = [x x in urllist if not r.match(x)]

which outputs 

['api.amazon.com/', 'fakedomain.com/']

i'm trying make output ['fakedomain.com/'] because wouldn't match regular expressions in ignorelist

several issues here:

  • re.match searches @ start of line. expressions not built that. use re.search.
  • your assigning result in loop: wrong logic.

i do:

import re  ignorelist = ['(?:\.)amazon\.com(?:\/(?:.*))',             '(?:\.)google\.com(?:\/(?:.*))']  urllist = ['api.amazon.com/', 'fakedomain.com/']   finallist = [x x in urllist if not any(re.search(r,x) r in ignorelist)]

so finallist contains urls not matching of regexes of ignorelist

result:

['fakedomain.com/']

note didn't "compile" regexes, may gain speed doing when testing lot of domains.

What is happening when Matlab is starting a "parallel pool"? -

running parallel cpu processes in matlab starts command parpool() according documentation , function: [creates] special job on pool of workers, , [connects] matlab client parallel pool. this function takes bit of time execute, on order of 30 seconds. in other multi-cpu paradigms openmp, parallel execution seems totally transparent -- i've never noticed behavior analogous matlab (granted i'm not experienced parallel programming). so, happening between time parpool() called , when finishes executing? takes long? parallel computing toolbox enables run matlab code in parallel using several different paradigms (e.g. jobs , tasks, parfor , spmd , parfeval , batch processing), , run either locally (parallelised across cores in local machine) or remotely (parallelised across machines in cluster - either 1 own, or 1 in cloud). in of these cases, code run on matlab workers , copies of matlab without interactive desktop. if you're intending run on remo...
