python - extracting text from tags in html using beautifulsoup -

-

This is the part of the HTML code that expresses the information that I want to remove from a webpage. Remove the name and the value between the B tags. The result I hope is such a list is: [on, DVI, 396,2035,2551] 

  ... 
 Power: & lt; B & gt; Current & lt; / B & gt; & Lt; Br> & Lt; Br> Source: & lt; B & gt; DVI & lt; / B & gt; & Lt; Br> & Lt; Br> Lamp runtime: & lt; B & gt; 396 & lt; / B & gt; Hours & lt; Br> Lamp Balance: & lt; B & gt; 2035 & lt; / B & gt; Hours & lt; Br> Total operation: & lt; B & gt; 2551 & lt; / B & gt; Hours & lt; Br> & Lt; / Div & gt; ...   
 What I tried was:   import from b4  beautiful soup urllib2 url = 'IP address here' html = urllib2 Urlopen (url) .read () soup = beautiful soup (html) main_div = soup.find ("div", {"class": "txt"}) data = main_div.findAll ('b'). Text   
 What's wrong? FYI, I am starting one, please stand by me.   
 
 
 Try  
  data = [main_db for bststring .findAll ('b')]

I do not think this is a relativant code. Can anyone tell me what should I do? I have already installed something to remove the password but Solver is still asking for password and I can not get rid of it! itemprop = "text"> Solver Excel is add-in If you want to delete it, then Excel Application & gt; Options & gt; Add-ins & gt; Search for 'Go to' button and gt; Uncheck the solver on the list like press something (I can not give you the exact path because I have the Polish version of Excel). Trying to open Solver's VBA code is not good because it There is allegedly copyright. Besides, I do not think Solver creates any disadvantages while working with Excel or VBA.

github - Teamcity & Git - PR merge builds - anyway to get HEAD commit hash? -

-
I have a team city build project with Gitbab VCS route, I have been triggered for both / head on PR and / Merge the referee. The annoying thing is that you can not do anything useful with the merged hash - it is not present in Gitobb. I want to exclude newsgate packages with head in gutub comet situations in the version number along with Hewash (Newsaging 7) for the music build, but against head hash. However, I can not see a way to get the head hashes while constructing that merge. I just want to head because it's useless - we only care about merge. (PR - Pull Request) This command works reliably while running One on / merge is git log --no-merge -1 ---- = '% h'
