Holmes | Concise scaffold of Koa2 server application | Runtime Evironment library

I am learning web development, and I tried to do the exercise, but the answer given is different from mine. May, anyone please help me see what my mistake is.

Here is the code:

So, I'm using Python 3.7 and performing a data report using Jupyter Notebooks. I have a dataframe, floridaDtFinal, which has the following columns:

...

I'm having the following results from my sql query:

id sp_firstname sp_lastname member_firstname member_lastname 1 NULL NULL John Smith 2 Dejuan McLaughlin NULL NULL 2 NULL NULL Jack Sparrow 3 John Walker NULL NULL 3 NULL NULL Sherlock Holmes 4 Mellie Durgan NULL NULL 4 NULL NULL John Waston 5 Lucy Snider NULL NULL

Whereas what I need to achieve is this:

id sp_firstname sp_lastname member_firstname member_lastname 1 NULL NULL John Smith 2 Dejuan McLaughlin Jack Sparrow 3 John Walker Sherlock Holmes 4 Mellie Durgan John Waston 5 Lucy Snider NULL NULL

Basically, I need to somehow merge pairs of rows that sort of have nulls crosswise.

After looking through SO answers, I could only find variants of this problem when NULL values needed to be substituted by numbers, and in that case people used max function combined with group by.

However I have several joins in my table and my NULL values need to be substituted with strings, not numbers, so max wouldn't really work here (as I thought).

Here's my sql code:

I read a snippet and confusing and could not find the rules or principle to explain that,the output is Malibu,why not London,the adress: sherlock.address in let john = { surname: 'Watson', address: sherlock.address }; is to assign the value ofsherlock.adress to john.address,but not overwrite sherlock.adresswithjohn.address.How could I fiddle my hair.

I am working on a product page where the user has an option to filter on different boardgames. What I want to do is to give the user an option to filter on time, category of the game, number of players and age. When the user enters a checkbox on all 4 options there should be some games recommended based on the criteria. However when I check multiple boxes I get no result, what am I doing wrong? (I have more games in my file but post small amount)

Here's my code:

I would like to implement functionality for being able to search a QPlainTextEdit for a query string, and display all matched lines in a table. Selecting a row in the table should move the cursor to the correct line in the document.

Below is a working example that finds all matches and displays them in a table. How can I get to the selected line number in the string that the plaintextedit holds? I could instead use the match.capturedEnd() and match.capturedStart() to show the matches, but line numbers are a more intuitive thing to think of, rather than the character index matches.
