My original problem:
"I have created web scraping tool for picking data from listed houses.
I have problem when it comes to changing page. I did make for loop to go from 1 to some number.
Problem is this: In this web pages last "page" can be different all the time. Now it is 70, but tomorrow it can be 68 or 72. And if I but range for example to (1-74) it will print last page many times, because if you go over the maximum the page always loads the last."

Finding your element with
class name doesn't seem to be the best idea..because of this. Same class name for all the next elements.
I don't know what you are looking for exactly because of the language. I suggest..you go to the website>press f12>press ctrl+f>type the
xpath..See what elements you get.If you don't know about
xpaths read this. https://blog.scrapinghub.com/2016/10/27/an-introduction-to-xpath-with-examples

You can use the annotate function to add text labels in the plot. Here is how you could do it:
I have 2 sets of data, let's say,
Platform. Both have attributes, say,
I need a way to compare, in Excel, the attributes for each element within both sets. For example, if Platform A requires Hammering and Drilling, and Worker A has Drilling, Grinding and Hammering, he'd be accepted for platform A. Worker B only has Drilling, so he'd be rejected at platform B.
The following spreadsheet illustrates this clearly:
In the sheet, "Canta Baila Pinta" are the attributes. The solution I've come up so far is:
Generate a string for each
Platform, which equals to its attributes
How do I compare both strings as if to ask, "Does string B contain any element not present in B?"
Furthermore, this code is not dynamic... how would you go about making it so that any newly added attribute got processed automatically, without user intervention?...

Apparently, I have a problem with my code. I run the below module with Python 3.6.6 Shell. I want to check whether elements of size 4 exists on list a_list and copy them to b_list. There is only one such element ('3m7n'), but it is decomposed in 4 others ('3', 'm', '7', 'n'). Why?...

Since your renderer is now acting as the default render for all the columns, you need to take into consideration how to handle them as well...

This is the most horrible XML I have seen for a long time.
Once you've parsed this XML into a tree, you will find there is a text node containing:
I am working on a project where our database is on svg format. Now, the weird thing (I don't know much about image formats) is that the image looks totally different if I open it on a computer program like Image Viewer, ImageMagick or Pinta, to how the image looks when I open it on a browser (be it Mozilla or Chrome). I am attaching an image (converted from svg to png) for convenience and you can see that the difference is really big if you open it on a browser compared to a normal program (if you download it and open it on your computer).
Now, I opened it on Python to see what is going on, and apparently the image is on RBGA format. I thought to convert it to RGB, and did it using the following code:...

In fact, SVG and PNG are totally different.
SVG (Scallable vector graphics) is not a standard image format : the image is not stored as an raay of pixel (or derivative), but as a vectorized format. To display it, you would have to render the vectors into pixels, then display them. The big assets of this approach are the quality vs. size : for illustrations, you can have a fantastic quality for almost nothing in size, however, it requires more time to process, and the decoding is very different from other image formats, thus it is often not supported by image viewers, and the renders can depend a bit on the renderer.
PNG (Portable network graphics) on the other hand is still based on pixel, and is very widely supported.
As for your question, your image have an alpha (transparency) channel. When converting it to RGB, you are getting rid of this transparency, which opencv translates into a fixed color. Here, this color is (0,0,0), that is to say black.
