I'm trying to create a command where a random meme is shown from a json. Unfortunately I can't do it ... I can do it using random.choice normally but since I'm a lazy person to update the code I always created a command that would allow me to add them in a json. So I have to be able to randomly extract the main key of my json. How could I do?

code:

I need to extrapolate a series of values ​​through XPath queries from XML files that I report at end of the page.

With a query like the following one, I get all the values ​​relating to, for example, the "Ragione Sociale Destinatario" attribute

I need to extract a series of values ​​through XPath queries from XML files that I report at end of the page.

In particular, I'm trying to find a query that allows me to select the values ​​related to the attributes, using the naming of the attributes themselves.

I am able through the following query, to read the values ​​of the first, second, third attribute etc..

Given the following file:

I am facing an optimization problem and I would like to find an algorithm capable of solving it.

Hyphotesis: the total sum of files size is at least greater than 15 MB. So total size is [15 MB; +∞]. For simplicity think of infinity as 100 GB,

Problem: I have a list of files with size between 3 KB and 4 MB. I have to zip those files and I need to guarantee that the sum of files size before zip them together is between 15 MB and 150 MB. There is any known algorithm to deal with this problem? In order not to have an algorithm to much costly in terms of computational requirements it is acceptable not to minimize the number of chunks (so each chunk is not mandatory to be as big as possible).

Thanks, Giuseppe

recently i've been really struggling with this , i thought maybe someone can help me with it , here is the problem:

I have a dataframe that represent what a client listen (music) , one user_key = one client , one client can have many rows .
