friend | Adds fine grained visibility semantics to Ruby | Datepicker library

I have a text file called listofhotelguests.txt where hotelguests are stored line by line with their first names separated by && as a delimiter. Can someone explain how I can have my Python program read it so it associates john with doe, ronald with macdonald, and george with washington?

My expected outcome I'm hoping for is if I prompt the user for their lastname to make sure their a valid guest on the list, the program will check it against what it has in the file for whatever the firstname they entered earlier was.

So if someone enters george as their first name, the program retrieves the line where it has george&&washington, prompts the user to enter their lastname and if it doesn't match what it has, either say it matches or doesn't. I can figure the rest out later myself.

Assuming there is nobody with the same names.

I know I have to split the lines with &&, and somehow store what's before && as something like name1 and whats after && as name2? Or could I do something where if the firstname and lastname are on the same line it returns name1 and password1?

Not sure on what to do. Python is one of my newer languages, and I'm the only CS student in my family and friend groups, so I couldn't ask anybody else for help. Got nowhere by myself.

Even just pointing me in the direction of what I need to study would help immensely.

Thanks

Here's what the text file looks like:

I am using Formik for a bunch of admin console forms that I have in my application. So far I did not have this use case.

My Formik forms use one of 2 custom components, either a Myinputtext(input box) or a MySelect(drop down). I dont have a need for any other components so far. Here is how my Myselect component looks like.

My code should print the number of all the words replaced from Z's to Y's, using a while loop.

I have a pair of iterator, and I would like to use ranges::views::filter(some_predicate) on it (with the pipe operator). AFAIU I should first convert my pair of iterator into a view. I tried to use ranges::subrange(first, last) to do so, but I’m getting horrible error messages.

Note1: I’m using C++14 and range-v3 version 0.9.1 (the last version compatible with gcc-5.5). If the solution differs when using C++17/20 and/or when using C++20 std::ranges, I’m also interested to know what changed.

Note2: I find the documentation of range-v3 severely lacking, so I’m using cppreference.com. If you know a better documentation, I’m very interested.

EDIT:

In my real code, I’m wrapping a java-style legacy iterator (that has a next() method instead of operator++/operator*. I’m wrapping them in a C++-compatible wrapper. Then I tried to convert that wrapper into a view, and finally filter it. I reproduce a minimal example on godbolt. This use iterator_range as suggested, but it still doesn’t compile (see the second edit below).

My implementation:

I am trying to dynamically generate the following html table, as seen on the screenshot

I was able to manually create the table using dummy data, but my problem is that I am trying to combine multiple data sources in order to achieve this HTML table structure.

SEE STACKBLITZ for the full example.

The Data looks like this (focus on the activities field):

Sorting data from huge lists with two levels of keys is helpful for interpreting dataset and calling by couple or one level of keys some slice of data, especially when creating plots.

I use a very naive and, I guess, inefficient way to create from a 2D-list of data a dict of dicts (two levels of keys) that returns a list of data. How to make this code more elegant, possibly faster and more readable? I guess using collection module but I didn't find a smart way.

Example:

I have been studying and learning PHP and MySQL and I have started a system that I'm developing for a friend's little school and to help me to improve my learning. I basically have in this case a table with the names of the students (tb_std) and another with the names of the teachers (tb_tch). The work is to distribute these students among the teachers in a new table, which is the way I think it will work better (tb_final).

1. I basically need each student to have a randomly chosen teacher so that the distribution is numerically even among the teachers.

In this example, I have 7 teachers and 44 students. Using SELECT query I did the operations to find out how many students would be for each teacher (add/division/mod), but how to make this draw to play in this new table I have no idea where to start.

How to remove VIM (completely) and change my mac command line editor to sublime?

I've spent the last three hours reading the same links on "how to remove VIM" only to get "how to remove MacVIM and reinstall it fresh" Or "How to remove Vim so I can reinstall it on Ubuntu"

My old laptop was fortunate to have a friend remove it but my new machine still has it installed.

I wish VIM would die in "words redacted to excessive profanity" dumpster fire while a hobo "words redacted to excessive profanity" to put out the fire

I've lost way too many hours trying to learn that outdated neckbeard elvish piece of UX trash so I want it gone. No, I'm not touching emacs.

Please tell me there is a way I can switch to sublime or am I permanently cursed to have this confusing black screen of death pop up when I try to git push or git tag stuff?

My original goal was to tag a git and push it but vim comes up and I can't figure out how to speak elvish.

I've been using PyCharm for a few years and love the interface but I need to dig deeper and a TDD Django book for class uses the terminal, it wants me to git -a "comments" so I need your advice.

So now I can't learn TDD Django because vim, MacVim and eMacs users flood the internet but I can't remove it nor figure out how to work it.

I've tried brew uninstall macvim which doesn't work because I have vim not macvim

I also tried sudo uninstall vim no luck as this is zsh mac not ubuntu

I tried brew uninstall vim to get No available formula or cask with the name "vim"

I've searched SO five times and keep getting the same links. Alternates I've tried brew uninstall ruby vim

per this post https://superuser.com/questions/1096438/brew-upgrade-broke-vim-on-os-x-dyld-library-not-loaded I tried, no luck.
