You can try to row bind them, simultaneously renaming the columns of df2

By adding that const to the end of that member function you're making it a const member function, meaning that it cannot possibly modify any of your member variables. Because calling a non-const member function could modify the object, you can't call it if the object is const.

std::set's erase member function requires that operator() be const to stop it from modifying the object's in their set without you realizing.

If any member function can be const then it should be const, just like any variables you declare or take in as arguments.

This is a solution with requests and regex to find the data that you are looking for.

Hi I m not sure about this but try changing the resolution on your phone. https://www.technobezz.com/how-to-change-screen-resolution-on-samsung-galaxy-s20-ultra/

There is no bug and Delphi returns proper value in PixelsPerInch.

PPI OS will return for the purpose of scaling your application is not the actual PPI value of the actual display device, but virtual pixel density.

For developing applications the PPI value you need is the one that OS gives you, not the actual PPI value of the display device.

Everything you need to know is baseline PPI for the OS and current PPI or the scale factor. Using those numbers you can then calculate number of scaled pixels from some baseline pixel value.

For instance, if your control baseline width is 100 pixels and screen scale is 150% from the baseline PPI then your runtime control size will be 150 pixels.

Different operating systems have different baseline PPI.

Calculation:

The quicksum method expects a generator expression or a list, not a single variable. Similarly, addConstrs also expects a generator expression. Hence, your first constraints should be written like this (note the extra bracket)

There is no sort_values ​​in groupBy (object created by groupby).

Wouldn't it be possible to get the desired data by simply sorting in three columns? Something like:

Note: Your Question needs more clarity to get specific answers. So I just wanna show up two options that will deal with your comment and will help to get closer. They are based on an available product in moment of request

I want to get spesific one let's say , processor model and memory size only.

Simply select the span taht contains your attribute and get the text from its direct sibling:

TLDR: you're not measuring what you think you're measuring;

88 and 90 are logical pixels per inch (see this enum and the docs for GetDeviceCaps):

Logical pixels per inch isn't the same as how many pixels per inch your monitor has. A point (eg 12 pt font), is 1/72 of an inch (in the real world). That's just the physical definition of it. So as far as your computer is concerned, whatever size a 72 pt font is on the screen is an inch (a logical inch). That's slightly compounded by your resolution settings. Since fonts (or anything) don't display the same size on different monitors, you can set your device to a scaling factor, DPI. This is D(ots) P(er) I(nch), but in this case the inch is a logical inch. So if you have your DPI set to 144, then the computer uses 144 dots per logical inch and that's what you're going to get back from LOGPIXELSX and LOGPIXELSY.

IF you want to figure out your PPI, then you can use this calculation:

The manufacturer has told you the diagonal is 28", but you can check that with GetDeviceCaps, using HORZSIZE (4) and VERTSIZE (6). This will be in mm, so to convert to inches you divide by 25.4. Once you have that, you can get the diagonal with the pythagorean theorem. From there, you can get the resolution of the screen in pixels with HORZRES (8) and VERTRES (10), then use the pythagorean theorem again to get the diagonal in pixels.

All that's left is to divide the diagonal in pixels by the diagonal in inches.
