caltech | Some of scripts I used for solving problems | Learning library

I am trying to access a dataset from python available here

In the API documentation, there is no information on how to sign in using username and password via script. Upon manually entering the API URL into a browser

https://ev.caltech.edu/api/v1/sessions/caltech/ts

I have to manually enter the username: DEMO_TOKEN and password: and click on sign in to get the JSON response from the server.

How do I programmatically do that in python?

Below is my snippet which doesn't work

I'm reviewing and experimenting with outlier flagging strategies, and keep running into references to Sn and Qn from Rousseeuw and Croux in Alternatives to the Median Absolute Deviation.

They sound quite excellent, and seem to be widely used in academic and applied stats across disciplines. I checked Google Scholar, and that paper has over 2,100 citations.

The appealing feature of this technique is that it isn't heavily impacted by asymmetric distributions. Which is what we've got, most of the time. Sometimes quite extremely.

This is of course available in R, but I'm not a stats person, we don't have server-side access to R (or Python), and would like to do some searches directly in Postgres. I haven't been able to find anything in any SQL idiom, and am hoping that some stats lover out there has some Postgres code up their sleeve.

Like the Title says, I am trying to read an online data file that is in .tbl format. Here is the link to the data: https://irsa.ipac.caltech.edu/data/COSMOS/tables/morphology/cosmos_morph_cassata_1.1.tbl

I tried the following code

I´ve been building a bot and it works exactly as intended, but only for one Tweet. Then, it waits 60 seconds, and, if it doesn´t find a new Tweet to reply to (since it´s configured to reply to the most recent Tweet), it throws an error (it´s 400 as in "400: Bad Authentication Data", but I think the issue is not that, since the bot posts on Twitter once without any issues. However, I do think it´s possibly some kind of Bad Request error). Whenever it crashes, I can just run in my command "python (botname).py" and it works once if there is now a new Tweet, but then, it crashes again. I want the bot to run properly by itself, so I would really appreciate some help! This is the code in my file:

I am a beginner at Twitter Development and Python programming in general, but recently I have been trying to build a bot that, when tagged in reply to a Tweet, finds keywords and uses Google to deliver some info from reliable sources regarding the topic of the original Tweet. However, I have encountered one major problem while programming: API doesn't get created since the code triggers the error "only unicode objects are escapable". I have used module Config to set my Twitter API credentials as environmental variables and that seems to work fine on its own. Before trying to run the bot, I activate my virtual environment and export the env variables, so I do not think this issue has to do with incorrectly setting those variables, but I would not say I am certain about that either! The code goes this way:

I wanted to let the user make a choice, like the example below:

My strings look like the following (each row is one exemplrary string):

I have a sbml model from Reactome, you can download it from https://reactome.org/content/detail/R-HSA-156581 and clicking sbml. For the , some of it have attribute of , and I'm trying to use libsbml or cobrapy for doing that.

My code read the sbml file, but how to get the attribute for ?

I am reading about exception support in C++, probably the result applies to other languages as well.

There is lots of stuff going on, I am a bit overwhelmed. My question is during the unwinding process, does C++ require help from kernel (e.g. setjmp/longjmp as mentioned in comments, these two functions don't involve kernel, however my question remains the same)? Or the entire process happen only in user space?

I could understand the unwinding of a local thread (think setjmp/longjmp) but is unable to grab how unwinding is done for remote thread.

If all the unwinding magic happens in user space, how can one thread modifies another faulty thread to send it over to handling code without kernel help? Since I believe the thread context information (task struct) lives inside kernel and disallows modification directly from user space, without access to thread context, how is it achieved? Thank you!

Update: It looks like I have some fundamental misunderstanding about the task struct. Just bumped into a slide about signal handling (signal handlers) (http://users.cms.caltech.edu/~donnie/cs124/lectures/CS124Lec15.pdf), upon entering a signal handler, the kernel stack is empty, all context information lives on user stack. I suppose one can use signal to communicate with other faulty thread to unwind? If that's the case, does it mean C++ exception support requires kernel help since generating signal is a kernel call?

Update: As far as the question goes, I am satisfied by Paul's answer. I would like to summarize my understanding on the topic in a broader sense, based on my reading on the comment/answer, please correct me if I am wrong.

C++ exception framework sdoesn't specify particular implementation method, below summary is what I would think it's "common".

There are three sources of exception object, the resulting unwinding is implemented as below:
