kandi X-RAY | sistine Summary
We turned a MacBook into a touchscreen using only $1 of hardware and a little bit of computer vision. The proof-of-concept, dubbed “Project Sistine” after our recreation of the famous painting in the Sistine Chapel, was prototyped by Anish Athalye, Kevin Kwok, Guillermo Webster, and Logan Engstrom in about 16 hours.

QUESTION
I want to find products
and for each product attach deals
to it. A deal
is a product
from same collection, yet based on some common properties.
So as per my requirement pipeline should return documents, for each document find other products those aren't same as current, but have equal detail.duration
. But even though I've many docs with same duration, deals
are always []
. Could you please figure out the issue with my pipeline?
Following is the aggregation pipeline I'm running: I've added filter _id $in just for clarity based on shown documents below. This isn't a part of real pipeline $match query.
...ANSWER
Answered 2022-Feb-20 at 11:36The $match query syntax is identical to the read operation query syntax; i.e. $match does not accept raw aggregation expressions. To include aggregation expression in $match, use a $expr query expression.
And you need to use $$
to get the variable value.
To reference variables in pipeline stages, use the "$$" syntax.
Change the $match
stage in the pipeline as:

I have a data object that I want to put in URL API to fetch it using Axios, I've done my research but I didn't found any solution to convert this to an Url endpoint
This is simply my data objects :
...ANSWER
Answered 2021-Apr-25 at 01:02There are many options to do that. For static data i often use https://gist.github.com/.
Process:
- Create valid JSON from your javascript object. For example:
JSON.stringify(data, null, 2)
. - Paste the valid JSON text into the gist.
- Give it a file name that ends with .json
- Create the gist.
- Now just select the raw button and use that url for doing your get request.
Here i've created a public_url_endpoint with your data.
QUESTION
My team and I (newbies to python) have written the following code to generate spotify songs related to a specific city and related terms. If the user inputs a city that is not in our CITY_KEY_WORDS list, then it tells the user that the input will be added to a requests file, and then writes the input to a file. The code is as follows:
...ANSWER
Answered 2020-Oct-20 at 21:32When your if
-statement is executed, you return a list of items and feed them into the display_tracks()
function. But what happens when the else
-statement is executed? You add the request to your text-file, but do not return anything (or a NoneType
item) and feed that into display_tracks()
. display_tracks
then iterates of this NoneType
-item, throwing your exception.
You only want to show the tracks if there actually are any tracks to display. One way to do this would be to move the call of display_tracks()
into your main
function, but then the same error would be thrown if no tracks are found to your search-terms. Another solution would be to first check if your tracks
are not empty or to catch the TypeError
-exception with something like
