I have this table that gives the names of the father and the children:

This second table tells who the children of each parent are, for example Geoffrey and Gabriel are Frank's children, and George, Gordon and Heather are Geoffrey's children:

I have tried in various ways to find a way to make a query that gives me the name of the father given the name of one or more children, for example if they give me George and Gordon the query should give me Geoffrey; of course if they ask me to obtain the father of Gabriel and Gordon the result of the query must be Null because these two children (Gabriel and Gordon) do not have the same father. Is there a way to do this query in sqlite3? Thanks in advance

I need find the average grade of all the students in the university and create custom exception while finding the average in the Arrays.asList. Exception should be thrown if int warCraftGrade< 0 or int warCraftGrade> 10. I have the following code:

I have a list of names and a group assigned to them as dictated by the A, B, or C letters. What I want to do is return all members of group A.

I am using a regex to find all lines that end with A, I then need to print the names of those individuals, not including the group (A, B, C)

I am running into a few issues:

1. The very last entry is in group A, however this is not the end of a line but end of file and is being ignored.
2. Some records contain a space before the end of line indicator and are being passed over.
3. I only want to print the name and not the group.

In Python's Flask-Admin for database table viewing/administrating, I need the view to open automatically to the last page of the paginated data.

Important: I cannot simply sort the records descending so the last record shows first.

Here's what my simple example below looks like. I'd like it to start on the last page, as pictured.

Here's some example code to reproduce my model:

Hello experts: I'm looking at so-called 'COVID-19 bubbles' inside pro cycling - I've compiled a list of riders for each team and a list of each race they've done. There are about 30 riders per team, and there have been a few dozen races after the sport started up again in July.

I'm stumped right now on how to proceed with analyzing the data or if this structure is even the right approach.

My end goal is to have a sort of Venn diagram of which riders raced together the most, one for each team, to visualize if they stuck to these bubbles (eg eight riders doing the same six races, and a different group of eight riders doing a different list of races, etc.)

Feel free to tag if duplicate/inappropriate etc. But a hand up would be appreciated!

My dataframe looks like such for one team:

I have a script that parses an XML file looking for certain attributes. However, when I try to define an attribute that doesnt exist, it throws an error. What is the best way to resolve this?

For example, this code looks for all works given by an API.

I need some help here. I'm trying to merge 2 dataframes (WIDE.2018 and WIDE.2015) with different number of columns and rows. Sorry I can't share the data. Both have the a similar set of columns with spatial coordinates (lon and lat). I'm trying to merge both of them by the best unique pairs (something such as optimal) or by nearest with replace=F (I'm using an analogy to MatchIt terminology). I only could handle a cbind that finds the closest distance but allows repeating observations.

As mentioned by Geoffrey(thks!), I'm looking to find the optimal 1:1 matching that minimizes euclidean distance across all matches, ensuring that each point has only one match in the other data.frame (with some points being unmatched in the longer data.frame).

I have a yaml file that looks like this:

I have a SQL table that contains some of the following data:
