python - Link Fetching List -


so i've asked many questions regarding 1 subject, , i'm sorry. it.

so have code:

import urllib import urllib.request bs4 import beautifulsoup import sys collections import defaultdict  m_num=int(input('enter number of monsters up: ')) x in range(m_num):     name=input("enter monster's name: ")     url_name=name.replace(' ','_')     url=('http://yugioh.wikia.com/wiki/card_tips:{}'.format(url_name))     page = urllib.request.urlopen(url)     soup = beautifulsoup(page.read())     content = soup.find('div',id='mw-content-text')     links = content.findall('a')     link_lists = defaultdict(list)     link in links:         link_lists[x].append(link.get('title')) all_lists = list(link_lists.values()) common_links = set(all_lists[0]).intersection(*all_lists[1:]) print('common links: ',common_links)

what i'm trying how many number of monsters user specifies how many lists creatd. each list filled links specific site. , in ned lists compared see if have similar strings inside of them. (hopefully makes sense).

so problem i'm having when run , gets print('common links:',common_links) part prints out last list. doesn't compare lists nor recognize other lists created.

can lend helping hand? i've been troubleshooting , i'm stuck.

link_lists refers new dictionary on each iteration. exclude it: put all_lists = [] before for x in range(m_num) loop. , replace last 3 line in loop with: all_lists.append([link.get("title") link in links]) note: don't need know m_num in case:

all_lists = [] name in iter(lambda: input("monster name"), ""): # loop until empty name     # ...     titles = [link["title"] link in content.findall('a', title=true)]     all_lists.append(titles)

linux - xterm copying to CLIPBOARD using copy-selection causes automatic updating of CLIPBOARD upon mouse selection -

i've tried various ways coerce xterm (versions 285 , 292) copy selection clipboard clipboard whenever press ctrl-shift-c. promising way far has been, in ~/.xresources, put this: xterm*vt100.translations: #override \ ctrl shift <keypress> c: copy-selection(clipboard) \n\ ctrl shift <keypress> v: insert-selection(clipboard) ctrl-shift-v works perfectly, copying has nuance... if restart xterm, highlighting text puts things in primary clipboard; expected, proper, default behavior. if hit ctrl-shift-c, copies current selection clipboard clipboard. the bug, however, if highlight text after first time pressed ctrl-shift-c, you'll see highlighting copies both primary and clipboard. cannot figure out how stop xterm updating clipboard upon selection... , doesn't make sense me in first place. i said, @ specific point in time, copy selection clipboard... yet starts updating automatically upon selection after doing once... anyone have workaround...

c++ - qgraphicsview horizontal scrolling always has a vertical delta -

Image
i've subclassed qgraphicsview custom canvas used in cad application. i've reimplemented qgraphicsview::wheelevent check keyboard modifiers control key and, if control key pressed, zoom. i'm trying implement horizontal scroll when user holds shift , uses wheel. the problem i'm having horizontal scrolling always scrolls 0.279. not huge problem, hugely annoying , points else being wrong. so, here questions: is right way implement horizontal scrolling? if not, is? how eliminate delta of 0.279? thanks in advance. code , sample output below void myview::zoom(int delta) { double factor = pow(1.2, delta/abs(delta)); this->scale(factor, factor); } void myview::scrollhorizontal(int level) { qpointf center = maptoscene(viewport()->rect().center()); qdebug() << "center: " << center.x() << ", " << center.y(); centeron(qpointf(center.x() - level, center.y())); } void myview::wheelevent(qwheeleve...
