Scraping html with Python or -


I give my arguments to students (microbiology and genetics) that "data" is a mess / and Python can help in that (Of course, in other languages ​​too), it is a practical kind of web-based data-gathering exercise.

I have noticed that there are some people who respond to questions related to Python between users with the supreme representative. Of naturally occurring questions:

I want to retrieve the representative growth rate for pythonostas on the current overweight and steak overflow, so that it can be guessed from time to time or Will you go ahead or? about what ? Is it trivial because the increase for these people has reached all limits?

More commonly, in the absence of the API for the query (which I do not think) there is no option to pattern the URL of the pages, to load those pages with Python and then HTML scraping? I know that there is probably no general view, but I am interested in how people will face this problem.

Edit: @fiszardaldStile: Generally, there really is just one (customized) example.

There is a completely useful monthly "data dump" of the stack, overflow, example under the Creative Commons license (For the first time - "at least one month" below the "My thumb" of several links). My average weekly representative for this kind of analysis is more useful than the screen-scraps, with respect to any other poster, such monthly amount of data.

If you want to screen-scrape (other ;-) site, and it does not violate its policies or their robots.txt files, Python offers many excellent options One is from the beginning - and you will not have too much extra work to do, because the example.

sql - dynamically varied number of conditions in the 'where' statement using LINQ -

I am using my first project LINQ (in mvc), so maybe there's something very simple that I remember. However, a day of searching and experimenting does not work, so it works. I am trying to write a LINQ query (Linux to SQL) in which in many cases where the statement is different from an OR or an AND. We do not know how many conditions are going in the query till runtime. This search is for filter control, where the user can choose multiple criteria for filtering. Select from table where table.col = 1 or table.col = 2 or table.col = 7 .... 'Other number of conditions Before I just create the SQL query as a string, while looping over all the situations. However, it seems that there should be a good way to do this in LINQ. I tried to use Expression trees, but they had a second thought for this moment on my head, where the lambda function was to be executed inside the statement such as: values ​​for matchingRows = matchingRows for each value Where (function (row) row.c...

asp.net mvc - Dynamically Generated Ajax.BeginForm -

I have a problem with ASP.NET MVC Ajax forms. I generate many Ajax form in a table such as: & Lt; Input type = "submit" name = "activity" value = "add activity" / & gt; & Lt;%}% & gt; & Lt; / TD & gt; & Lt; / TR & gt; & Lt;%}% & gt; So far so good. When I post one of those forms, it gives a partial view in a div, and in this new partial view a new Ajax Beginnform (which is not in Genesis form) This second Ajax Beginnorf is exactly like the ones I got on the table, but when I post it, I do not get the "Ajax Post", but a normal post that sends me to a new page, I do not know whether the two Ajax forms What is the reason for the difference between, why is it the "dynamically generated" Ajax form behaves like a normal HTML form? By the way, I know that I can do it in different ways using javascript, but I would like to understand whether it can only be done using MVC helplars and Ajax lib...
