QUESTION
I have a data frame with two columns. cnn_handle
contains Twitter handles and tweet
contains tweets where the Twitter handle in the corresponding row is mentioned. However, most tweets mention at least one other user/handle indicated by @
. I want to remove all rows where a tweet contains more than one @
.
ANSWER

QUESTION
I'm making a little game where robots fight each other. The robots have a table in the database where their match scores are recorded. Each robot has its own home island where it can face opponents. The opponents will have their own island. Each robot has its own island. The question is simple enough, but it could lead to confusion, so I briefly explain step by step:

ANSWER
Answered 2021-Dec-07 at 20:57Your problem wasn't quite condensed enough to reproduce, or to see the desired output, but your basic approach is fine. You may run into issues with misspellings, in which case maybe use an edit distance with a threshold for determining whether to take out the stopword. Here's my version of your code that seems to do fine

QUESTION
I first want to parse a large text file and collect all the necessary views before I finally display them. I have it working with an array of AnyView
but it's really not nice since it erases all types.
Basically, I just want a container to collect views inside until I finally display them.
So I was wondering if I could do something like this:
...ANSWER
Answered 2021-Nov-07 at 12:03So it seems that it is not possible, Group
, VStack
or similar are not meant to be stored like that. Instead, one has to store the content in some other way and then dynamically recreate it in a ViewBuilder
(or just body
).
This is how I ended up doing it:
Separate class for the parser, which uses two separate arrays. One to keep track of the content type and order (e.g. 1. text, 2. image, 3. divider etc.) and then one for the Texts
only, so all the markdown formatting can be saved for later use in the ViewBuilder
.
QUESTION
I have a character string of 400 URLs called URLs. I have a loop that has been working for a while but now it takes way too long. It used to just report the url as an error and then I would omit but its is getting hung up.
...ANSWER
Answered 2021-Sep-08 at 18:55I think the issue I am running into is due to the open connections. The script would get progressively slower and I feel it was due to the old connections. Here is a simple loop that closes out all of the connections. I will know when I run a particular report again if this is the solution but it has seemed to help so far.
QUESTION
I have a word game here made with javascript,
I play against a robot that guesses a word from a directory of words it has. If the guessed word have a matching letter and matching index it turns blue and gets displayed.
If any letter only exist in the guess word but not at correct index it turns orange.
The robot now randomly guesses the words and doesn't do anything with the blue or orange letters. I want the robot to filter the word directory it guesses from with the letters that are correct or exist in the guess word.
I can store those letters in two variable but I'm having scope problems to filter the word directory from the scope these variable
...ANSWER
Answered 2021-Aug-04 at 09:42You have too much code too see where the problem is happening. Is this the filter you are looking for?
