I want to filter a df with respect to working days.The df is:

I have an array of complex dict that have some value as a string "NULL" and I want to remove, my dict looks like this:

I have an application where I am receiving a string with some repetitive characters. I am receiving input as a String. How to remove the characters from specific index?

I'm pretty new to Python and opencv, and I would like to use opencv to crop frames from a video. The work flow is as follows: I opened up an image and get some coordinate values from mousecallback function. Since the video was taken with a cell-phone on a tripod, I would expect the region of interest should be fixed in space. Therefore, I can use the coordinate to batch process other frames. The first cropped image is done and saved as expected but I have a problem processing the other frames.

I need to find a way to combine elements by key in a new array, such that I end up with just one key containing all values for that key (found elsewhere in the parent array). This will make more sense when you see the example below:

How to do that? i mean it is some kind of search on the matrix. I need to search search_matrix on main_matrix. Special rule is: if search_matrix is a included in beginning 4 elements of main_matrix then it can be a output. I mean if search_matrix is not in main_matrix's beginning (4 elements) it cannot be a in output_matrix. and element order is most important. elements must be in order.

There are a lot of examples of converters to JPG and i am trying to change one for my needs but i need little help please. The requirements are:

1. It should be an AppleScript Droplet. I am using Script Editor ( for some reason Automator can't run a simple droplet drag and drop function for me ).
2. The output folder for the JPGs should not be prompted by the user .. but set as a variable in the code permanently and easly changed.
3. The quality ( compression ) of the converted JPG should also have to be easly customisable in the code.
4. The converted JPG files have to be converted to Color profile Adobe RGB 1998 if necessary.

I know Image Events allow us to set the JPG compression like :

save openedFile as JPEG with compression level (low|medium|high)

but unfortunately i need more customisation.

A shell script will help me to set the level from 10 to 100 but unfortunately i can't implement the shell script properly. Little help please about points 3 and 4. Thank you !

I could not get the a nested logic to work. I need to combined data from 2 table and return it to the request. I do not want a join table as I need to return an individual record from tableA first then combine with tableB record before it is returned. Below is my simplified code

Using CakePHP 4.1.6

I have two tables in my database called Categories and CategoryChanges. The Categories table is simple in that it contains a list with ID's and names of several categories, e.g.
