rabbit | RabbitMQ wrapper for steadway/amqp that supports auto | Pub Sub library

I've got a list of strings, for example: ['Lion','Rabbit','Sea Otter','Monkey','Eagle','Rat']

I'm trying to find out the total number of possible combinations of these items, where item order matters, and the total string length, when all strings are concatenated with comma separators is less than a given length.

So, for max total string length 14, I would need to count combinations such as (not exhaustive list):

• Lion
• Rabbit
• Eagle,Lion
• Lion,Eagle
• Lion,Eagle,Rat
• Eagle,Lion,Rat
• Sea Otter,Lion
• etc...

but it would not include combinations where the total string length is more than the 14 character limit, such as Sea Otter,Monkey

I know for this pretty limited sample it wouldn't be that hard to manually calculate or determine with a few nested loops, but the actual use case will be a list of a couple hundred strings and a much longer character limit, meaning the number of nested iterations to write manually would be extremely confusing...

I tried to work through writing this via Python's itertools, but keep getting lost as none of the examples I'm finding come close enough to what I'm needing, especially with the limited character length (not limited number of items) and the need to allow repeated combinations in different orders.

Any help getting started would be great.

Background

This is the client side Javascript, where I make a post request to update the respective tables with the form parameters. My database has two tables-Rabbit table, and MyStuff table, and MyStuff table holds a foreign key to the rabbit table. Now, I first update the Rabbit table by making a post request which not only updates the Rabbit table but also updates the value of the rabbitID variable in the server, and the second request updates the MyStuff with the respective form parameters, and also makes use of the rabbitID variable just updated.

I get a bunch of hits when I search for this but I have ended up going down rabbit holes that were WPF-specific or something like that. My environment is Xamarin Forms Android/iOS/UWP. It is something of an experimental/educational project so there are no totally "hard" requirements for a solution. The ItemTappedEventArgs gives me the contents of the row, but not the specific item or column.

The question is this: if the user taps on a particular item in a ListView ViewCell, how can I determine which specific column or control they tapped?

Here's the relevant Xaml: (RowStyle has only appearance properties like FontSize and Margin.)

I wanted to replace np.nan with None values, but weird behaviour occurred:

I am making a game in python, and am displaying an image. I would use pygame, but the effects I am making won't be used in pygame. I looked it up and used pillow because it requires the least code. Open vc looked a little complicated.

Running a test in Fitnesse gives:

Could not complete testing: fitnesse.slim.SlimError: Error SLiM server died before Header Message could be read.

When using Slim RunnerW.exe to debug my test I get an exception:

System.BadImageFormatException: Could not load file or assembly 'file:///c:\path\assemby.exe' or one of its dependencies. The module was expected to contain an assembly manifest.

I used ProcessExplorer to check and RunnerW.exe was running in 64bit mode. My code is compiled with "Any CPU", the only difference with another working project is that it is a .net 5 (core) project using FitSharp 2.8.2.1 NuGet package.

After enabling the FusionLog it was clear that it could not load my main test assembly. This is part of the log:

I'm trying to add a GUI to the predator-prey simulation. It can allow users to choose which simulation(species involved) they want to do, set the simulation field size they want, and show the progress of the simulation and result.

The question is after I generate the field, I can't reset the simulation or run the next step or run the next hundred steps by clicking the buttons I set, not to mention show the progress of the simulation.

Here is the code of my GUI Class:

I am trying to build a strictly typed factory for my TS project and having issues figuring out if it is possible to automatically infer a schema from the passed argument.

I have an array of variable numbers. I have another array that I want to be the of labels for the numbers array.
