QUESTION
I have found a code that orders the elements of a list according to the grades specifid in the tuples that constitute the list. I cannot understand how it works though: shouldn't be specified somewhere that the parameter data is referred to the students list? Thanks
...ANSWER
Answered 2022-Feb-06 at 21:25Well here you did specify in your code. You have wrote a function (anonymous) and called in students.sort(key=grade)
what key does is use the function given to sort it by. So you are sorting by the 1st index element, which is the letter grade. Hope this helped, have a nice day!

Here is code to read the data out of the tables in a SQLite database:
...ANSWER
Answered 2021-Oct-30 at 07:37Declare it as TEXT
. If you declare it as STRING
, it has affinity of NUMERIC
, not TEXT
Have a look at Datatypes In SQLite, especially the last sentence in the examples.
And the declared type of "STRING" has an affinity of NUMERIC, not TEXT.
This will cause SQLAlchemy to fail. Have a look also at this SO question
QUESTION
I recently picked up a project a little out of my comfort zone and I'm not sure how to approach part of it. This may be a duplicate, but I haven't been able to find any solid answers in my searching. I've worked in other languages, but am new to python/pandas which is what I'm being requested to do this in.
My end goal is an automated script to send out an "In Approval" table to managers of all active orders waiting to be approved. The part I'm having issues with is tackling the actual data. I import the data from a CSV, and my initial plan was to break different columns of the CSV into 2 dataframes. 1 with the active approvals and 1 with all the order data. I was then going to iterate through the Approvals based on a unique ID and run it through a class that queries and returns orders matching that ID. Then I found out that Pandas doesn't iterate like I'm used to in other languages, where I'd just run it through a ForEach.
So my question would be, is there a best known method to iterate through and query data like this, or is there some Pandas magic I'm missing that will allow me to sort and pull out data I can format into an HTML table for presentation?
EDIT Here is a simplified and bleached version of the data I'm working with and what I'm trying to turn it into. I did this as a table for ease of readability.

QUESTION
This most likely doesn't have anything to do with VueJS but I'm mentioning it because it's the environment that I am using.
I'm new to IndexedDB and decided to go with Dexie to remove a lot of the complexity. I've started off with creating a very simple database with a simple where
query. All of Dexie's functions are return promises so inside my Vue component I have the queries wrapped inside an async/await component method.
When I go to invoke the function however, the wrapper function returns a promise rather than awaiting the Dexie query. If I console.log
the query or assign the query's return value to a component variable the await works, just not when I use the function's return value directly.
This is most likely some misunderstanding that I have with promises that I'm overlooking, but why is my function returning a promise even though I'm awaiting the Dexie query?
...ANSWER
Answered 2021-Feb-03 at 05:44It's because async
functions always return a promise. From the MDN docs:
Async functions always return a promise. If the return value of an async function is not explicitly a promise, it will be implicitly wrapped in a promise.
Statements that you use await
on don't do this:
Await expressions suspend progress through an async function... The resolved value of the promise is treated as the return value of the await expression
So when you log such a statement, you see the value. But if you return that value and log it, it will have been wrapped in that implicit promise.
