urllib2 - Unable to download file,Python xlsx File download zero bytes -


after running code,downloaded file 0bytes. tried writing response too,also tried using buffer

what doing wrong,what else can try? please help

import urllib2 bs4 import beautifulsoup import os import pandas pd     storepath='/home/vinaysawant/bankifsccodes/' def downloadfiles():     # remove trailing / had, gives 404 page     url='https://rbi.org.in/scripts/bs_viewcontent.aspx?id=2009'      conn = urllib2.urlopen(url)     html = conn.read().decode('utf-8')     soup = beautifulsoup(html, "html.parser")      # select elements href attributes containing urls starting http://     link in soup.select('a[href^="http://"]'):         href = link.get('href')          # make sure has 1 of correct extensions         if not any(href.endswith(x) x in ['.csv','.xls','.xlsx']):             continue         filename = href.rsplit('/', 1)[-1]         print href         print("downloading %s %s..." % (href, filename) )         #urlretrieve(href, filename)         u = urllib2.urlopen(href)         f = open(storepath+filename, 'wb')         meta = u.info()         file_size = int(meta.getheaders("content-length")[0])         print "downloading: %s bytes: %s" % (filename, file_size)         print("done.")         file_size_dl = 0         block_sz = 8192         while true:             buffer = u.read(block_sz)             if not buffer:                 break              file_size_dl += len(buffer)             f.write(buffer)             status = r"%10d  [%3.2f%%]" % (file_size_dl, file_size_dl * 100. / file_size)             status = status + chr(8) * (len(status) + 1)             print status,         f.close()          exit(1)   downloadfiles()

i tried

import urllib urllib.retreive(url)

i tried using urllib2 urllib3 well.

i not pandas , urllib2 since there no answer question. think problem trying download first url 

url='https://rbi.org.in/scripts/bs_viewcontent.aspx?id=2009

you define here , doesnt change 

u = urllib2.urlopen(url)

after try download thing associated url 

buffer = u.read(block_sz)

instead of them guess should try download href try change this

u = urllib2.urlopen(url)

with that

 u = urllib2.urlopen(href)

recursion - Can every recursive algorithm be improved with dynamic programming? -

i first year undergraduate csc student looking competitive programming. recursion involves defining , solving sub problems. understand, top down dynamic programming (dp) involves memoizing solutions sub problems reduce time complexity of algorithm. can top down dp used improve efficiency of every recursive algorithm overlapping sub problems? dp fail work , how can identify this? the short answer is: yes. however, there constraints. obvious 1 recursive calls must overlap. i.e. during execution of algorithm, recursive function must called multiple times same parameters. lets truncate recursion tree memoization. can use memoization reduce number of calls. however, reduction of calls comes price. need store results somewhere. next obvious constraint need have enough memory. comes not-so obvious constraint. memory access requires time. first need find result stored , maybe copy location. in cases, might faster let recursion calculate result instead of loading somewher...
