QUESTION
not sure if my title is exactly waht I want to accomplish but it was a guess. I'm trying to see if something like the following is possible in PGSQL.
Basically, I have a set of data that I want to pull no matter what. But, if certain columns of data arent null, then I want it to join another table and pull data referencing that data. So, for example, let's say I have data like:
User_Accounts:
userid companyname first name 25df Test Company 1 Bob 921f Test Company 1 Lawrence 882s Company test 2 NULL 8234 Test Company 1 Cleo 8244s Company test 2 Paul 825q Test Company 1 Bruce 5552 B Alpha Company LennyBaseball_Rosters:
userid baseball_team company position 25df Atlanta Aliens Test Company 1 P 882s Boston Bruisers Company test 2 DH 8234 California Craisins Test Company 1 1B 8244s Tampa Titans Company test 2 P null Tampa Titans Test Company 1 P 5552 Tampa Titans B Alpha Company 2B 5552 Tampa Titans B Alpha Company SS 921f California Craisins Test Company 1 P 825q Boston Bruisers Test Company 1 PHow would I perform a query to get a result like:
userid baseball_team company first name position null Tampa Titans Test Company 1 null P 25df Atlanta Aliens Test Company 1 Bob P 825q Boston Bruisers Test Company 1 Bruce P 921f California Craisins Test Company 1 Lawrence PSo essentially, inserting the firstname & lastname field if and only if userid is not null? And then to order by userid null first and then in order? Thanks for the help.

I have a problem about implementing recommendation system by using Euclidean Distance.
What I want to do is to list some close games with respect to search criteria by game title and genre.
Here is my project link : Link
After calling function, it throws an error shown below. How can I fix it?
Here is the error
...ANSWER
Answered 2021-Jan-03 at 16:00The issue is that you are using euclidean distance for comparing strings. Consider using Levenshtein distance, or something similar, which is designed for strings. NLTK has a function called edit distance that can do this or you can implement it on your own.

QUESTION
I have 3 tables with two columns each (image). I want to make the table editable (edit row, add rows, delete rows) and I'm a little lost. Each table row has an edit button, and at the end of each table there is an "add" button.
If I want the modal title to either say edit or add would I need to make 2 different modals or is there a way to do this in JS?
How would I do about making the table editable? I tried putting together some JS (see below)

I'm still super new to coding so don't judge my code to harshly but any advice is appreciated!
I'm trying to build a budget tracker app using electron. I have a list of transactions (table) where I would like to let the user add, edit and save rows. I got it (more or less) working in codepen, but in the context of my full html file nothing happens and I cant figure out why.
I linked the js file (called table.js) before the closing body tag.
I've tried wrapping my JS in

QUESTION
I am working on a project in which a user selects 1 choice from 3 random options. There are twenty total rounds of this. I set the "draft" or selection up on one file, where the rounds are separated into divs and when the user picks an option from the first round, then that round disappears and a new round appears using "display:none." I recently added localStorage commands to the file, and ever since I did this, the code no longer successfully switches from round to round. When a selection is made, it stays on the same round and the "display:none" command does nothing. What should I do differently?
Here is the JS file:
...ANSWER
Answered 2020-Jul-24 at 23:36The HTML and the Javascript provided here are incomplete, but the most likely cause I can think of is if your HTML document didn't contain elements with the IDs of:
- overall
- cumovr
- qbTeam
I had to add these as well as as a shuffle method and "showTeam" and qbselect2 and qbselect3 in order to get the example to run. Once I did that, it worked, so it seems to me that you probably have errors in your console relating to one of the elements above, which is stopping the execution of your Javascript method BEFORE the display:none is reached.
EDIT: Sorry, yes I also had to add a the data for the half-backs and allow the team selection block to be initially visible and remove the stray brace. I think you may have damaged the code in trying to reduce it for this example.
QUESTION
So I wrote a script to scrape a table on a website - NFL roster for 32 teams, over 4 years. The website, however, only shows one team, and year at a time. So my script opens the page, selects a year, scrape the data, then moves on to the next year, and so on till all four years of data are gathered. It then repeats the process for the other 32 teams.
Now, I'm new to web scraping, so I'm not sure that computationally, what I'm doing is the best way to go about it. Currently, to scrape one year of data for one team, it takes roughly 40-50s, so in total, roughly 4 minute per team. To scrape all the years for all the teams, that comes up to over two hours.
Is there a way to scrape the data and decrease runtime?

Answered 2020-Jun-24 at 13:50You can improve by not using Selenium. Selenium (while it works) will naturally run slower. The best way to get the data is through the API where it renders that data:
