snail | Continuation-ready container algorithms from STL algorithms | 3D Printing library

Trying to figure out how to code something simple.

I have a dataset that has observations for individuals (small invertebrates) in my experiment over time, including the week, individual's id #, and the observation data of interest (parasite counts). I also have a cumulative total over time for the parasite counts, grouped by the individual's ID, which is what I will actually want per week.

I would like to drop individuals that, by the end of the experiment, never had an observed sample that was positive for parasites, because they were not successfully infected. My plan was to have a binary indicator column that told me if an individual didn't have a positive sample by the end of the experiment, based on the final cumulative total per individual id (it's possible that an individual could give a positive sample one week but not the next, so a 0 cumulative total is more safe). Then I would simply subset the data by the positive binary column, removing individuals who were never positive.

A very simplified version of my dataframe would look something like:

Newbie question:

So this code here

I can't find a way to get it back, I even made it super big but it still wasn't there, none of the image loading or drawing on to screen was touched when coding the collision so I'm just really confused. Can someone please have a look and tell me what's happening?

full code here:

Hello I am French so excuse my bad English please, I created a generation of land with a seed with prefabricated gameobjects but they spawn from column to column so I would like to create this but starting from the center to outside like a snail but in square

I partially succeeded, the first image shows the generation in columne but also the desired final result with the generation in snail and the second shows what I managed to do therefore in snail but my pieces of land are square it looks bad

• First:
  
• Second:
  
• It works like:
  
• And I want it Work like:
  

I'm very new to coding and while testing to see if this contract would compile I ran into this error. I've tried adding a set of parenthesis to the function but it feels like the more I try to listen to brownie the stranger it begins to look to me. Have I missed something? This is the error:

contracts/AdvancedCollectible.sol:28:18: ParserError: Expected '(' but got identifier function createCollectible(uint256 userProvidedSeed, string memory tokenURI) ^---------------^

What I have written so far is below:

So I have this Data and trying to do kruskal.test() over a list containing dataframes

Question: How can I know that an image variable has successfully loaded an image from an image url?

The relevant javascript code I have been using is below (I am coding a Chrome extension). I want to grab a random image from an array of images, so I can use (inject) the random image on a webpage. But since I am grabbing the images off some websites that have tons of free images, I want to make sure the random image is not blocked by the free images website for whatever reason (and if it is blocked, then I will try another random image from maybe another site). I need to know that img.src contains an actual image or not. I am new to javascript, reading a book on it I just got yesterday-- do I need the semicolons or should I just ditch using semicolons? (I come from a background coding in C/C++)

I have two separate data frames, and I want to do the same thing to both. I want to pair the columns according to the first substring before the underscore (a, b, x, y), and then if a value in the first column contains a word, but the corresponding row in the totals column is null, i want to update the total to a zero. I want to update the data frames and then output them both separately.

The list contains different sandwich ingredients, such as the following: ingredients=['snail', 'leeches',] and I have to create a loop that prints out the list(including the numbers: 1 snails 2 leeches
