            You will need to have two separate projects; one for your React front end, and a totally separate Python project for your Flask API. They will communicate by HTTPS generally, so you'll set up endpoints in Flask, and call them using a library like axios on the React side.

            Modification points:
            • When I saw your script, it seems that uniqueemails of EmailSheet.getRange(2,4, uniqueemails.length,1).setValues([uniqueemails]); is [["value1,value2,,,"]] that value1,value2,,, is a string value. In this case, the values are put to a cell. This is due to var unique = unq.join();. In order to put the values to the row direction, the array is required to be like [["value1"],["value2"],,,].

            For this, how about the following modification?

            Next.js - SWR hook question about dedupeInterval and refreshInterval
            Asked 2021-May-28 at 21:13

            I'm using SWR hook along with next.js for the first time and i've tried to get some answers about something but i couln't get them, not even with the docs.

            Questions: So, i know SWR provides a cache with your data, and it updates in real time, but i'm kinda lost between two options that you have to use the hook. So, normally, you have dedupeInterval and refreshInterval

            ...

            ANSWER

            Answered 2021-May-28 at 21:13

            Now, what are the differences between these two ?

            The difference is that:

            • refreshInterval is defining a time after which a new request will be sent to update your data. eg. every second.
            • dedupeInterval is defining a time during which if a request was already sent for a specific data (ie. a data having a specific key), when rendering a component that asks for a new request to refresh that data, the refresh will not be done.

            Deduplicating means eliminating duplicates, ie. making potentially less requests, not more. They give an example in their documentation with a component that renders 5 times another component called that uses the swr hook. But the actual request will be made only once because that rendering will be within the default 2 seconds time span.

            If i have two request with the same key, it will update after two seconds ? Is it the same as refreshInterval ?

            No, the dedupeInterval set to 2 seconds will not automatically update the data. It will update it only if a component using the same key with the swr hook is rerendered after the 2 seconds. Or if you haven't deactivated other updating mechanisms like on focus and the user puts the focus on your component.

            With refreshInterval there would be an API call every X amount of time, as long as the component is still mounted, even if it doesn't rerender and the user doesn't interact with it.

            If i use refreshInterval, would I have problems with performance ? Since it's making a request in very short periods of time.

            Yes, if the user opens your page and does nothing but reading content during 20 seconds, and you have set the refreshInterval to 1 second, there will be 20 API calls to update that data during that time. That behavior may be useful if your data changes every few seconds and you need to have the UI up to date. But clearly it can be a performance issue.

            The reason why the refreshInterval is disabled by default whereas the dedupeInterval is set to 2 seconds is to avoid too many API calls.

            How do I write a measure in this power pivot table that will only sum values next to a unique value?
            Asked 2021-Apr-30 at 12:24

            I want to sum 'hours' in this table. Every 'item's' hours should be counted once, even if it appears twice. So Group A has 12.25 hours, in the example below.

            Here is the source table:

            A PowerPivot gives me:

            So it's double counting rows where 'item' occurs twice, of course.

            Because the 'hours' for different 'items' aren't the same, I'm not sure how to write a DAX measure to make this work in the pivotable (this is just an example, real dataset is the same problem but much larger). I tried

            =([Sum of Hours]/COUNT([Hours]))*DISTINCTCOUNT([Item])

            However it's not the correct calculation. It gave me 9.84375 for group A (right answer 12.25) and 47.53125 for group B (44 is correct).

            You can see this from a deduped list (for unrelated reasons, it's not feasible to dedupe the list).

            What measure (or combo of them) is going to give me what I need?

            Framing the problem correctly would help you figure it out.

            "Deduplication" suggests altering the table - starting with a state with duplicates, ending with a state without them. Usually done in three steps (getting the rows without duplicates into temp table, removing original table, renaming temp table).

            "Removing rows with duplicated column values" also suggests alteration of data and derails train of thought.

            What you do want is to get the entire table, and in cases where the columns you care about have multiple values attached get the highest one. One could say... group by columns you care about? And attach them to the highest value, a maximum value?

            Deduping a list of lists runs afoul of the Borrow Checker
            Asked 2021-Apr-18 at 01:25

            I am trying to dedupe a list of lists. I already have a procedure that will dedupe a single list without a problem. However, now I want to concatenate multiple lists and dedupe at the same time and the Borrow checker is up to its old tricks.

            In the below code, the only important thing to know about FeelValue is that it is Clone but not Copy. The key goal is to accomplish concatenation and deduping with only one Clone call. The end result is to return the deduped Vec, which must have stable ordering. It is easy to do it with two clone calls: just change set.insert(&item) to set.insert(item.clone()) and alter the type of the HashSet.

            I am happy to drain or otherwise mess with the Vec's inside the RefCells if need be.

            Your problem isn't with the borrow checker per se, its with RefCell. The Ref returned from borrow() must stay in scope for the duration of any references derived from it.

            One trick is to collect the Refs from all the RefCells into a Vec so that all stay in scope while iterating over the references:
