I am trying to convert a String into proper JSON notation. This string, got some correct indexes (with [idx]), and some incorrect indexes (with dot notation .idx. with these last ones starting by 1, instead of by 0). Is there anyway to "handle" captured groups using python re library or similar?

This is what I have:

I have to parse lists of names, addresses, etc. that were OCRed and have invalid/incorrect characters in them and on the state postal code I need to recognize the pattern with a 2 character state followed by a 5 digit postal code and replace any non numeric characters in the postal code. I might have OK 7-41.03 at the end of a string I need to remove the hyphen and period. I know that re.sub('[^0-9]+', '', '7-41.03') will remove the desired characters but I need it only replace characters in numbers when found at the end of the string and only if preceded by a two character state wrapped in spaces like OK. It seems if I add anything to the regular expression as far as a lookbehind expression then I can't seem to get the characters replaced. I've come up with the following but I think there must be a simpler expression to accomplish this. Example:

I am trying to get the function name from a string: for example str = "this is a function name this.function() and there are more text" and I want to extract first instance of this.function() from it. The str is not consistent and the function name can be anything and can be repeated but it always has a dot in the middle and trailing opening and closing parentheses with or without parameters. How can I do this using python re?

What I want to make, is to create a record of this class:

I have a WPF app, linked to a SQL-server. I am using the MVVM-light package (I do actually have Prism.Core installed, but I'm not sure if I'm using it or not.... new to MVVM).

There's a DataGrid, bound to an ObservableCollection. I have been trying to implement the PropertyChangedEventHandler, but I can't seem to get it to work.

I have a Delete button bound, and I am able to remove rows, but when I re-open the form, the changes does not carry over.

I tried to change the binding-mode for the DataGrid from OneWay to TwoWay. With OneWay, the changes does not carry over when I re-open the form. With TwoWay, I get this error message when opening the child form (which contains the DataGrid):

System.InvalidOperationException: 'A TwoWay or OneWayToSource binding cannot work on the read->only property 'licenseHolders' of type 'Ridel.Hub.ViewModel.LicenseHoldersViewModel'.'

So, If I then add a set; to my public ObservableCollection licenseHolders { get; }, the program runs, but the previous problem persists, like it did when there was a OneWay mode configuration on the DataGrid.

What do I need to do to get this to work without communicating directly with the Sql-server, which would defy the whole point of using this methodology in the first place?

I am building an app following the Rest Countries API challenge from frontendmentor (https://www.frontendmentor.io/challenges/rest-countries-api-with-color-theme-switcher-5cacc469fec04111f7b848ca). I have run into a problem. When clicking on the router link in countryDetail.js, the url changes but the component doesn't get re-rendered unless the page is refreshed.

CountryDetails.js

I'm trying to understand how the "fetch" phase of the CPU pipeline interacts with memory.

Let's say I have these instructions:

I know this question has been asked multiple times but I cannot seem to find an answer. I have a component named DynamicTable which renders JSON as a data table. It has been tested in multiple other pages and works correctly. Here I have put it into a React-Bootstrap tab container. The data pull works correctly but the page is not re-rendering when the fetch is complete.

Here is the code I am using

I'm using express-validator to find out if certain user inputs match specific keywords. If any of the inputs are invalid, a POST request to my db should not be made. If all of the inputs pass, then the POST should go through. The user should be re-directed to a /submitted view when the inputs are valid or invalid.

When none of the inputs are valid, the POST is not made and the db is not updated (which is good, since I don't want the db to have invalid data), but the issue is that the page hangs and never reloads (has to be done manually).

I have an if/else statement below that says what should be done if the data is invalid. The console says that applicant.end() and res.end() are not functions. Is there something else that I can write that'll "stop" the request but do the redirect?
