kandi X-RAY | clumpy Summary
this tool can manipulate or generate large swaths of image data stored in numpy files. it's a sandbox for implementing operations in c++ that are either slow or non-existent in pillow, scikit-image, or the scipy ecosystem. since it's just a command line tool, it doesn't contain any ffi messiness. feel free to contribute by adding your own command, but keep it simple! add a cc file to the commands folder and make a pull request. this is just a toy library. for serious c++ applications you might want to look at xtensor (which can read / write npy files) and xtensor-io. to achieve huge speed-ups with numpy, see numba. build and run clumpy. generate two octaves of

QUESTION
On my frontend, I use an Angular (11) Material Datepicker element to let the user pick a date. The formatting for this is done using the MAT_DATE_LOCALE
provider, and it is dd-MM-YYYY
, so 23-12-2020 for today. This Datepicker is linked to a FormControl using reactive forms.
While I am content with how the date is represented to the user, I'd like to send the date in a YYYY-MM-dd
format. It seems the Datepicker is setting the value of the FormControl to a Date object and I don't know if I can change this. I could of course create a method to change all the fields I need changed before POSTing, but this seems clumpy and I feel like it could be done more elegantly.

array.filter(x => x.title != null && ... etc)

QUESTION
Thanks for taking a look at my question. I have created a script using BeautifulSoup and Pandas which scrapes data on projections from the Federal Reserve's website. The projections come out once a quarter (~ 3 mos.). I'd like to write a script which creates a daily time series and checks the Federal Reserve website once a day, and if there has been a new projection posted, the script would add that to the time series. If there has not been an update, then the script would just append the time series with the last valid, updated projection.
From my initial digging, it seems there are outside sources I can use to "trigger" the script daily, but I would prefer to keep everything purely python.
The code I have written to accomplish the scraping is as so:
