python - urllib.error.URLError: <urlopen error [Errno -2] Name or service not known> - 


from urllib.request import urlopen bs4 import beautifulsoup import datetime import random import re  random.seed(datetime.datetime.now())  def getlinks(articleurl):     html = urlopen("http://en.wikipedia.org"+articleurl)     bsobj = beautifulsoup(html)     return bsobj.find("div", {"id":"bodycontent"}).findall("a",href = re.compile("^(/wiki/)((?!:).)*$"))  getlinks('http://en.wikipedia.org')

os linux. above script spits out "urllib.error.urlerror: ". looked through number of attempts solve found on google, none of them fixed problem (attempted solutions include changing env variable , adding nameserver 8.8.8.8 resolv.conf file).

you should call getlinks() valid url:

>>> getlinks('/wiki/main_page')

besides, in function, should call .read() response content before passing beautifulsoup:

>>> html = urlopen("http://en.wikipedia.org" + articleurl).read()

javascript - Why does running this loop 9 times take 100x longer than running it 8 times? -

consider code: test = function() { } t = new test(); (var = 0; < 8; i++) { result = t instanceof test; } if change number of iterations 8 9 , loop take 100 times longer complete in latest version of firefox (41.0.1). tested on 2 different pcs , magic limit 8. here jsperf test used: http://jsperf.com/instanceof-8-times-vs-9-times does have idea why might happen? seems specific instanceof . not happen if else object, example check property. note: filed bugzilla bug this. jan de mooij mozilla team has posted details in bugzilla thread . here's simplistic interpretation of highly technical answers: in i < 8 case, firefox smart enough hoist result = t instanceof test; statement out of loop (according tests, doesn't seem omit altogether). in i < 9 case, apparently doesn't optimization . why? reason not clear, related fact 9 iterations threshold above function considered "hot" enough run through jit compiler. i < 8 cas...
