QUESTION
I am making an app that has information about different woods, herbs and spices, and a few other things. I am including the ability to save their favorite item to a favorites list, so I have a heart button that the user can press to add it to the favorites. Pressing the button toggles the isFavorite property of the item and then leaving the page calls a method that encodes the data to save it to the user's device. The problem that I am running into is that it is not encoding the updated value of the isFavorite property. It is still encoding the value as false, so the favorites list is not persisting after closing and reopening the app.
Here is my Wood.swift code, this file sets up the structure for Wood items. I also included the test data that I was using to make sure that it displayed properly in the Wood extension:
...ANSWER
Answered 2022-Apr-11 at 20:19Your problem is that structs are value types in Swift. Essentially this means that the instance of Wood
that you have in WoodsDetailView
is not the same instance that is in your array in your model (WoodData
); It is a copy (Technically, the copy is made as soon as you modify the isFavourite
property).
In SwiftUI it is important to maintain separation of responsibilities between the view and the model.
Changing the favourite status of a Wood
is something the view should ask the model to do.
This is where you have a second issue; In your detail view you are creating a separate instance of your model; You need to refer to a single instance.
You have a good start; you have put your model instance in the environment where views can access it.
First, change the detail view to remove the binding, refer to the model from the environment and ask the model to do the work:

I counted birds on different dates and areas. Some birds got a tracking ID.
That gives my a table with this header. t1

I have 3 tables that I want to join. One table has fields that need to be broken out of one column to become two columns. Here are sample tables.

All of the A doors are counted together except the one that has no hinges. All of the B doors are counted together. Any part that's not a hinge or plate is ignored. Any material that's not a hinge or plate is ignored. Any door type that has no hinge or plate leaves those fields blank.

Any help would be much appreciated.

QUESTION
I have a task about clusterization in python. When I did this clusterization I need to check the result with business logic.
I dont see the pattern in solved clusters. Next, I decided to do post analysis with correlation. I take one cluster and calculate a correlation pairwise. In calculation I used whole feature unlike a clusterization when I used only 3. I got a high level of correlation from 0.99 to 1 in whole cluster. For me it means that algorithm watched the logic in cluster.
But, i did this clusterization to solved a problem with banks data (i wont to see the client's pattern like (issued amount > 50.000,age < 22, salary < 80.000 - this client, for instance bad)). And I cant see the business logic, for me it's random data.
With this description I have a question. How can i check the logic in the clusters except a simple self-checking ?
I think there are 2 reasons. First, my clusterization is bad and I need to write a new one. Second, the data is bad and I need to check data and do a post analysis
I did a BIRCH cluster with StandardScaler.
...ANSWER
Answered 2022-Jan-20 at 09:28All of verification methods are 'empirical'.
- You can compare the different methods of clusterization and choose the best one.
- The correlation comparison methods: a) If correlation approximately 1. You need to calculate a row's average and median. Next step you compare this two value and drop bads row. b) If corr are different in whole matrix. Calculate averages for all rows and compare the value and the mean average; choose god one like this 'value > mean(avg)'
QUESTION
I have variables, say variables A outside the functions. In one function, mine_function, a random integer is added to the separate variables in variables A. But when I call the inv_function() after calling the mine_command(), the variables A stay 0. They were not added. What do I do?
P.S. this is from one file. The main file imports these functions to the main file to run.
...ANSWER
Answered 2022-Jan-05 at 01:06This is due to int
s being an immutable data type. When you modify them using the +=
operator, it replaces the entire variable, rather than modifying the existing one. This means that if you look at the variables inside the inventory
tuple, they won't be changed, since they weren't updated.
You might want to consider using a dictionary data type to store your inventory, rather than a bunch of variables, since dictionaries are mutable.
QUESTION
I have a program, and one function is to sell an item that the user owns. It prompts the user to input the name (id) and amount, and it sells. But there are a lot of items the user can own, so there are lots of if else elif statements. How do I shorten this? (P.S. I am using Replit, and Replit currently has Python 3.8) Here is the sell function, for reference.
...ANSWER
Answered 2021-Dec-31 at 08:23You can reduce the branching a lot using dictionaries and objects for what you are doing. And it is the power of OOPs. Here is an example how you will remodel your code.

I am currently working with a large dataset I retrieved from the crossref API in which I retrieved information on scientific papers based on a DOI search.
Currently the large list contains of ~3500 elements. Each of these elements is a list of their own consisting of the metadata 'meta', the actual relevant data 'data' and an irrelevant list 'facets'.
This is an example of two of the lists based on two DOI's:

QUESTION
I am trying to build a feature in a Bokeh dashboard which allows the user to cluster data. I am using the following example as a template, here is the link:- Clustering in Bokeh example
Here is the code from this example:-
...ANSWER
Answered 2021-Aug-11 at 12:48I don't know sklearn
but comparing both your examples I can see the following:
- the
Select
is a Bokeh model which hasvalue
attribute of typestring
. Soselect.value
is a string - the
dbscan
is an algorithm function
So when you do algorithm = dbscan
you assign an algorithm function to your algorithm
variable and when you do algorithm = select.value
in your second example you assign just a string to it so it won't work because string
doesn't have the fit()
function. You should do something like this:
