webcolors | A library for working with HTML/CSS color formats in Python | Theme library

If you really need Colours to be a class, then this metaclass just does it job - and seems fine. There is no problem at all in making use Colour inside it - there is no such thing as "metaclass code can not make use of any 'ordinary' class" - it is Python code as usuall.

The remark I'd do there is that maybe you don't need to use Colours as a class, and instead just create the Colours class, with all the functionality you need, and create a single instance of it. The remainder of the code will use this instance instead of the Colours class.

Yes, a single instance is the "singleton pattern" - but unlike some complicated code you can find around on how to make your class "be a singleton" (including some widely spread bad-practice about needing a metaclass to have a singleton in Python), you can just create the instance, assign it to a name, and be done with it. Just like in your example you have the "webcolors" object you are using.

For an extra-singleton bonus, you can make your single instance of Colours be named Colours, and shadow the class, preventing any accidental use of the class instead of the instance.

(And, although it might be obvious, for sake of completeness: in the "use Colours as an instance" case there is no need for this metaclass at all - the same __getattr__ method goes into the class body)

Of course, again, if you have uses for Colours as a class, there is no problem with this design.

After searching solutions to the main error message c++: error: unrecognized command line option '-R', I finally found it in this discussion.

What I did was searching for the relevant files using the mighty find method:

After some investigation, Propector supports Django, Celery and Flask, which means it automatically installs the Pylint plugins needed for it to support these frameworks.

Is it possible you have specified to use pylint-django? In order for pylint-django to inspect Django code it requires Django to be installed, prospector docs states it doesn't normally automatically detect your project's dependencies, but it states you can turn them off using:

I have found the error to this, I was not aware of the need to add my pdf elements into the document element before making any additions to it and .Complete() returning null was a result of this. I'll leave my question here for any future users needing the reference.

Apparently, you cannot run functions the way I initially thought with re.sub. I managed it in the following way (here with a folder of svgs):

Setup

Floating elements functionality in iText is based on the CSS concepts and the behaviour is quite similar. Let me explain some of the details here.

I'll first answer the second question. To get some spacing between image and the content that wraps around it, you should use margin properties for floated image. E.g. in your case it's image.setMarginRight(5). Floating elements make content wrap around them, however block boxes positioning is not affected, blocks are positioned as if there were no floats at all. Thus when you specify padding for the paragraph, it's still there but it's "under" the image.

Have a look at this HTML snippet that demonstrates the same behaviour that applies in iText layouting: https://jsfiddle.net/cah7uzed/2/ Pay attention at padding that works below the image.

The first of your questions is more tricky. The thing is that vertical alignment is applied for the whole content of the cell at once, treating all it's children elements as a single chunk. Therefore text is moved along with the top edge of the floating image while aligning this single big chunk.

Currently there is no out of the box simple solution for your use case. I think what you need is some kind of analog of CSS flex property, which allows to center-align all the blocks positioned in a row, but iText currently doesn't support it.

I can think of a workaround though. You can wrap paragraph with Div element with fixed height equal to the floating element height and additionally specify vertical alignment for this Div. If you want heights to be dynamic depending on the content, you can precalculate container's height like it's shown in this answer: https://stackoverflow.com/a/41788843/4495409. Technic shown there applies to all model elements including Paragraph.

In general case you would want to precalculate both floating element and paragraph heights and choose the bigger one. To simplify a bit, based off your specific case and assuming that you know that image height is going to be always bigger than text height, you can simply specify image height for the Div. In this case your code would look like this:

I found the answer by myself. Instead of adding header row while writing the document I added it in table creation itself and re-write the code as below:

Well in the end I uninstalled and reinstalled Anaconda. This seemed to do the trick as now cx_freeze builds an exe which works fine. Not sure what happened to my previous install of Anaconda.

Hope this helps someone as it drove me up the wall!
