CoT | Experiment Code for Paper CoT : Cooperative Training | Machine Learning library

Please help me, guys. I have the following:

I would like to make a table which can show sin,cos,tan,cot values of chosen degrees. As i said, i couldn't take the right answer of tan90 . I don't know how to change it to 'INFINITY'. I am waiting for your help ! :)

I tried to make some syntax checker for arithmetic expressions. So, one of the negative tests is: No operator between variable(or constant) and left brace. Something like that:

I've got a COTS product that requires we set a certain configuration property with a DNS name, rather than an IP address. Fortunately, our company standardized what the DNS names for that class of servers will look like. For example, an IP of 10.2.100.50 would have a DNS name of S010002100050.mycorp.com. That is, it takes each octet from the IP address, prepends enough 0's that the value has exactly 3 characters, and then appends the DNS suffix. Simple, right?

My problem is, I need to take the IP address and convert it to the DNS name so I can apply it during my automated server config. I'm not the most skilled at sed, but I thought it could be used to do this. Unfortunately, I can't for the life of me figure out how. I came across a couple of related Stackoverflow questions (question 1, question 2) that talked about pre-pending 0's, but try as I might I couldn't get it to work as expected.

Can anyone give some advice and guidance on how I can accomplish this?? Thanks!!!

I'm developing a little desktop application that lists the files in a given directory.

The table on the left gets compared to the table on the right. If anything on the right is missing, the text of the files on the left will turn red. Simple.

What I'm throwing at these tables is a path that contains multiple subfolders of images. These are saved as a variable so I cannot explicitly declare "omit a directory with this name".

Using this as an example:

I get this output:

And I'd like to get this output:

How do I get the find command to return ONLY the file names? No directory names at all. Is this possible?

As of now I have:

edit 9 Dec 2020: I have been asked to clarify the question. The best clarification I can offer is that ShadowRanger's code:

Python student here,

I have been studying up on basic algorithms and I am having some trouble fully understanding MergeSort. I believe I understand the divide and conquer approach, how namespaces are created within each loop cycle, and how the algorithm splits up the elements. Where I get a bit confused is in how it reassembles/merges the elements, successively taking on the sorted values.

I think I understand everything from results line 21 to 37. i.e. how nlist is transformed to [27, 43]. My specific question is regarding results line 38 and how righthalf which was [43, 27] at result line 21, takes on the value of nlist which is [27, 43] (results line 38).

As I do not see any variable assignment of nlist to righthalf,

i.e. righthalf = nlist is not in the code flow between 'results' lines 37 & 38

MergeSort Algorithm (with diagnostic print statements):

I have been following a guide step by step to create a Tkinter management system, however, my code still doesn't output a value when I add sweet quantities and click the total button to create a subtotal, vat, and total float output. I am new to coding and can't find a solution online or in the tutorial. Thanks, Mo.

I have a code below to calculate area and perimeter of a heptagon. The formula for it, area = (1/4)nk2 cot(π/n). As far as I know we can't use "cot" in C and according to my google searches, we should be using like 1/tan(x). But it's not working. Can anyone help and explain how to do that?
