siphon | simple program for moving files | Incremental Backup library

I want to embed a MetPy SkewT diagram in a PyQT5 GUI. The following code creates a SkewT diagram:

So I have two different tables, a users table and an articles table. The idea is to allow a user to rate an article, but only allow them to rate it once (possible change their existing rating too but I can come to that conclusion later).

As of now I just have the update value working to allow them to rate the article, but of course a user can rate an article as many times as they want.

To give you an idea of how I have everything working, when a user logins in, a session is created with their user information. So when they go to rate an article, I have the ability to check the user, I just don't know how to stop them from rating if they have already rated a specific article.

The user table consists of among other things their username and their unique ID

and the article table consists among other things the article contents, the article unique ID, and the articles rating.

I had some really sloppy ideas like when the user rates an article their ID gets stored into the articles row in some kind of "users who have rated" column, and then I can do a for loop or something to siphon out all the user IDs and then check if their ID exists in that articles entry but then each article would have a row with possibly hundreds or thousands of userIDs on it and there seems like there would be a more elegant way.

Any help or direction is appreciated :)

I built a python program that will siphon through my email and retrieve lat/long pairs of worksites that will be relevant for future analysis. At the moment I have the following dataframe returned.

I'm kinda new with Metpy. I've been trying to calculate the temperature advection with Metpy but it's been unsuccessful. Since I'm new with this package, I don't understand why needs to have units to work properly. When I calculate temperature advection I end with some weird lines on my maps and I don't know why. I think it's because of the units or something but I'm not sure. I attach my script below:

I am trying to plot recent sea surface temperature data on a map. I got it working when I downloaded the netCDF4 file, but when I try to access the file from https://www.ncei.noaa.gov/thredds/, I get a TypeError saying, "Input z must be 2D, not 3D". The downloaded file I used originally was from: https://psl.noaa.gov/ Here's what I have:

I am working with the NDFD forecast datasets and would like to assign lat and long within the array to give me the ability to plot the data outside of matplotlib. My versions are:

python 3.8,metpy 1.0.0,cartopy 0.18.0, xarray 0.16.2, siphon 0.8.0

In Python I'm using a class out of library. I only want to call certain functions if a certain parameter is set.

For example:

I followed the example here (https://unidata.github.io/python-gallery/examples/Precipitation_Map.html) but when trying to access the units I get a dimensionality error. I'm assuming this is to do with pint and the way it parses units and the fact precipitation is a rate. Any help would be appreciated

I am new to plotting and examining wx data using python. I started with this example 850 hPa temp advection and its failing at this statement.
