baka | GTK3 GUI for the pacman package manager

Hi I'm Matthew and I've been trying to code for two weeks and I'm having an issue with my questions. So for the first question I want to ask the user a question followed with two more attempts if they get it wrong, but I want it in a certain way for example "there are 100 bricks in a plane one falls out how many are left?" not a trick question 99 but if the user did get it wrong after answering I want try again printed after and if they mess it up again "try again" then if they mess up a third time I want a message to be shown that you failed. but I also want if you do get it correct a message will state that you got it right.

I have a type that can take the structure of 3 interfaces, but when using a property of 2 of those 3 interfaces, I get an error.

The action should have a token property when it takes the structure of IAuthSuccessAction interface, and an error property when it takes the structure of IAuthFailAction interface.

What do I miss?

After I try to apply a given suggestion from @Baka:

I have tried to create a type that changes depending on which enum's value is being used:

How can one create a function create_bigrams(l) that takes in a list l of strings and returns a dictionary, bigrams, that have strings of length two as keys and True as values? The keys that are strings of length two should come from the list l of strings and is a letter combination from these strings.

For example:

build_bigrams(['baka', 'kaka'])should give the dictionary {'ba': True, 'ak': True, 'ka': True} thus ba, ak and ka are letter combinations from the string 'baka' and 'kaka'.

I have been having issues making the joke function work in my discord bot it was working just fine yesterday but today i don’t know what’s happening and it’s just not responding to the joke command, i have tried changing the string names as well and it worked one time and responded to a word which didn’t exist in the code and that word was jokes which i don’t know how it reponded to it and it doesn’t respond to it anymore i’m really confused and don’t know how to make it work kindly help me fix this problem i will be thankful to you.

This is the error:

I have a help menu and some commands in it. There are some NSFW commands too and I want these commands to not show if the channel isn't marked as NSFW.

Here is my current code:

I'm trying to make the rectangle stay on the moving line. I heard that I would have to make the rectangle move at the same speed as the line. But I'm kinda screwing the speed up, so if anyone knows how I would fix the speed.

I am getting the following error:

java.lang.IllegalArgumentException: No available camera can be found.

when calling and instance method ProcessCameraProvider.bindToLifecycle(). See this in the context of the code below by searching for "------ Code Crashes Here --------------".

How do I prevent this error and subsequent crashing of the app? More specifically, how do I ensure the CameraSelector can return a camera instance for the Nexus 6?

It appears there is something wrong with the CameraSelector used in this call. If I set a breakpoint on the bindToLifecycle line, and debug up to that point and add a watch for `cameraProvider.hasCamera(cameraSelector) it returns false. Maybe this is not intended to return true until the bindToLifecycle method has been called. If so, how can I verify the cameraSelector object has been created sucessfully (successfully meaning it points to an actual camera object)?

In the creation of the cameraSelector object, I use the requireLensFacing method in the builder, so it appears the Nexus 6 hardware does not tag anything with these LENS_FACING_BACK or LENS_FACING_FRONT and therefore does not return any camera instance? Do I understand this correctly?

I should note that this error did not occur when the exact same code was run on a Nexus 5, which is why I am inclined to think it is a hardware issue.

I also tried the LENS_FACING_FRONT int, but had the same error. If I remove the requireLensFacing build component altogether I get a different error:

java.util.NoSuchElementException

I already have this working but looking to optimize this. It takes a really long time to extract the article data related to this because my methodology is using a for-loop. I need to go row-by-row and it takes alittle more than a second to run each row. However, in my actual dataset I have about 10,000 rows and it is taking a really long time. Is there a way to extract the full article other than a for-loop? I am doing the same methodology for every row so I'm wondering if there is a function in R similar to like multiplying a column by a number which is super quick.
