hamster is a Ruby library typically used in Artificial Intelligence, Dataset applications. hamster has no bugs, it has no vulnerabilities and it has medium support. However hamster has a Non-SPDX License. You can download it from GitHub.

efficient, immutable, and thread-safe collection classes for ruby. hamster provides 6 [persistent data structures][pds]: [hash][hash-doc], [vector][vector-doc], [set][set-doc], [sortedset][sorted-set-doc], [list][list-doc], and [deque][deque-doc] (which works as an immutable queue or stack). hamster collections are immutable. whenever you modify a hamster collection, the original is preserved and a modified copy is returned. this makes them inherently thread-safe and shareable. at the same time, they remain cpu and memory-efficient by sharing between copies. while hamster collections are immutable, you can still mutate objects stored in them. we recommend that you don’t do this, unless you are sure you know what you are doing. hamster collections are thread-safe and can be freely shared between threads, but you are responsible for making

ANSWER

You can chain a .reduce after d3.groups in order that the nested array is recast into a nested object.

You can initialize the reduce with {} so it returns an object. curr[0] for each array returned from d3.groups will be the animal. curr[1] for each array returned from d3.groups will be the array of the status and the original array of items grouped per the animal/ status logic.

Asked 2021-May-31 at 18:03

I have difficulties to properly export to a JSON table the content of a html table when it contains a select tag. I need the selected option value to be exported, not the full content of the select inputbox (ex: "Animal":"Dog\n Cat\n Hamster\n Parrot\n Spider\n Goldfish" should be "Animal":"Cat")

The html code I use is:

One way is use the index in the extractor. When index is one return the value of the select, otherwise return the cell text

QUESTION

How do I count the playerwins for my code

Asked 2021-May-17 at 09:11

Aye, so I have this assignment to make a rock, paper, scissor game. I did mostly everything right (maybe), but I can't figure out how to count the playerwins at the end when stopping a game of rock, paper, scissors. It is the one thing I am missing when running and stopping the code.

Playerwins are at the very bottom and the very top. The code is long as hell, but im new at coding and don't know how to make it less redundant.

...

ANSWER

Answered 2021-May-17 at 08:28

The first thing you need when you program any game is that you need a game loop, which runs the game until the user exits it. Interestingly, you opt for recursively calling main, which is also possible (although it could theoretically overload stack, which probably won't happen in this simple case but could be a real problem in a game that loops many times per second for a long time).

So the easiest fix would be to move the playerwins variable out of the main function (then you need to make it static as well) but the correct code that builds better habits for later work would be to use another while loop instead of recursively calling main.

Normally, beginners start with iterative code and discover recursion later, so it is nice that you discover it so early, but unfortunately that is not the correct case for it, but keep it in your pocket for other occasions.

so i'm fairly new to using python and I wanted to make a list of popular pets and have the person type in a number (that's assigned to an animal from a list of 10 in a dictionary) and print the correct animal from the number they typed in.

ANSWER

Answered 2021-May-09 at 15:58

Ok, two problems you have here.

First of all, a dictionary is like a door. You need a key to open a door. What is on the other side of the door is your value.

In your case, you want to access an animal, based on a number. The number will be a key and the animal will be your value.

So first step would be to reverse your dictionary key and values.

The second would be to change how you take an input and store it in a variable. Not like
