I'm using Scrapy and I'm having some problems while loop through a link.

I'm scraping the majority of information from one single page except one which points to another page.

There are 10 articles on each page. For each article I have to get the abstract which is on a second page. The correspondence between articles and abstracts is 1:1.

Here the divsection I'm using to scrape the data:

For example, with the example dataset below, how do I set a filtering condition using jupyter notebook where I can find out who has 2 or more results of "Number of Candies" more than or equal to 3.1?

Thus, the output after filtering should be

How might I create a map that has strings as keys and tuples ,of one or many elements, as values? The elements of the tuples are to be strings of phone numbers. Much like what I have in the following Python code:

I have already seen many threads with examples of how to do this, the problem is, I still can't do it.

All the examples have tables with extra data. For example somethings like this

I'm currently in the second half of a computer science class but I wasn't able to take the second one right after the first one. So I've forgot a large portion of my coding knowledge. I'm trying to re learn it all but it's quite tough without just going all the way back to the basics.

An assignment I'm working on currently is asking me to do the following:

Design a solution that requests and receives student names and an exam score for each. Use one-dimensional arrays to solve this. The program should continue to accept names and scores until the user inputs a student whose name is “alldone”. After the inputs are complete determine which student has the highest score and display that student’s name and score. Finally sort the list of names and corresponding scores in ascending order.

I wasn't really sure how to organize and start this but I went ahead and just started writing some code to at least make some progress and maybe figure something out.

The way I've set up my program doesn't exactly respond to the prompt as I was experimenting with array lengths and for loops to get reacquainted.

SO MY QUESTION IS, How would I make it so when users type "alldone" the program stops taking inputs and calculates the highest grade with the person who had it only using 1D Arrays.

Is it possible to take the names as a string and then insert the strings into an array?

Here is my code so far, It's not what the assignment is looking for but I just want to get some inspiration on some things I could do:

I have a dataframe like so:

Input:

I have a dataframe like so:

I have a dataframe where I want to replace all values of 999999 with another column value, while leaving all other values alone. Here is an example of what I have now:

Here is what I want the dataframe to look like:

Is there an efficient way to accomplish this?

Thanks in advance.

Maybe I'm being stupid here but I dont understand why in the below example the correlated subquery works but the simple subquery doesnt. Can someone explain why please.

In the sample database im working with the authors are listed in the authors table and the title_authors table gives information on if the authors have written or co written any books. au_id is the PK in authors and part of a composite PK in title_authors. if the royalty_share column is set to '1' that means the author was the sole author on a book.

How come the correlated subquery is able to give me the authors who have '1' in the royalty_share column, but the simple subquery just gives me all the authors regardless of what is in the royalty_share column?
