Given a list of lists (e.g. the input_ls below): Do you know of a function which gives me the minimal list of lists (as a dictionary), with which I can construct the initial input_ls by "adding up" those lists (e.g. the output_dict below)?

I am working on a project in which I need to post a new Course to my API. I tested this with POSTMAN and API works just fine, however when I try to post data using react fetch data is corrupted. While sending single strings like dishName: "pizza" works just fine and is shown in database I cannot manage to send an array of objects. I tried to do it in many ways like:

I am having a problem with having it printing out a response of each item in my list, but if I get rid of the loop responsible, I can't check a users input, for example, if they put 'almond', it will say it doesn't know, because in my list, it says 'almonds'.

That is why I do a loop through each element, so it will search for the word in the element, but the loop prints that it can't find the answer a few times (unnecessarily!) and then the answer.

I hope this is understandable, and here is my code:

Everything that I push into arr1 should have been removed from the mapping of arr2, but instead the new pushed value is returned. Why is that?

I am trying to extract set of keywords such as ['lemon', 'apple', 'coconut'] etc. from the paths such as "\var\prj\lemon_123\xyz", "\var\prj\123_apple\coconut", "\var\prj\lemonade\coconutapple", "\var\prj\apple\lemon"

The expected output is little complex:

keep in mind that the third row does not have the exact word which start with /, \s, \d or _ thats why there is no match. The regular expression is kind of like this: \s\d_/[\s\d_/]. I tried using:

df['Paths'].str.findall(r'[^\s\d_/]lemon|apple|coconut[\s\d_/$]', flags=re.IGNORECASE)

But it is still showing 'lemon' and 'coconut' in the third row.

Thank you in advance.

So I had a task to do a shop class, products class a basket class bla bla bla, I did all of this, tested, everything is working fine and that has nothing to do with the problem. Now what I had to do is create discounts and a chain of responsibility, like let's say I create 3 discounts and it goes through pointers and checks which one is suitable. So I did it, it does work, when I was debugging I checked, that it stops on the discount it needs to, returns me the price with the discount applied BUT THEN it somehow is going back by pointers and returning again what I don't need. I will make this more clear after I show the code and I will provide an example. So this is my Discount.h which holds a pointer to the next Discount and the main virtual countDiscount(); function that plays the role in all of this.

I want to separate this list into two different list. The pattern that I saw the fruit is the number 1. always followed by fruit, while animal placed between whitespace except the last one.

So basically I have an array of items : [ apple, banana , peach , pear , coconut , orange ... and so on ]

I want to display them in an embed but since embed has a character limit , I want to display only 10 elements per page and whenever the user reacts with arrow emojis - it will take them to the other page- so basically paginating an embed. But no matter how many ways I try , I cannot seem to do that- Help is very appreciated!

P.S - I deleted my codes out of frustration so I can't provide a code- well my code wouldn't be any help anyways-

Having a difficult time describing this which is probably why I'm not certain what function/what I'm looking for. Would appreciate someone describing what this function is called.

Basically, I have about a dozen .csv files, each with lists of a few hundred genes each. None of the lists includes all gene names.

What I'm looking to do, is to merge all those lists together and get a comprehensive list of all genes with an indication of which files said genes show up in. I don't need the values, just 1s and 0s to indicate if those names show up in said file is plenty.

I can already tell this may not make sense, so this analogy may help:

Let's say I have three files, Fruit A, Fruit B, and Fruit C. Fruit A has 2 apples, 3 bananas, and 1 orange. Fruit B has 1 apple and 1 coconut. Fruit C has 2 oranges and a lime. I want to merge it and produce a file that looks like this:

Any advice would be greatly appreciated.
