2-years in the making! Codename Mallow is a 4 player local/online versus multiplayer that I've been coding entirely in Python/Pygame. Tackled rope physics, particle engines, and other fun things. The demo launched today!! The source code is available, too. Enjoy :)

Codename Mallow is an adrenaline-charged versus multiplayer game with armless melee battles, one-hit-kill weaponry, and wildly unpredictable stages. Duel for Ninja Supremacy with up to 4 friends in local or online play. Demo & Source Code available NOW!

Demo / Code: [https://ancalabro.itch.io/codename-mallow](https://ancalabro.itch.io/codename-mallow/)

Website: [https://www.codenamemallow.com](https://www.codenamemallow.com/)

To anyone perusing the source code, be warned: I am self-taught and a giant hack. I have lots of bad habits, and my code is probably laid out pretty poorly. So I wouldn’t look at the code in this project as something to emulate. But if you think any of the in game effects are cool/interesting, access to the code should at least let you go in and figure out how I went about creating them. Hopefully someone finds this useful!

User Groups/Profiles in JupyterHub on Kubernetes

Is it possible to establish user groups or profile templates in JupyterHub? For instance, a normal user would get 2Gi of memory but a data science user would get 4Gi of memory and have a different image.

If not, is it possible to dynamically allocate resources? For example, a user needs more memory, can I add more memory to his pod?

My solutions for Cracking the Coding Interview questions

I spent my free time this lockdown summer going through many of the questions in the Cracking the Coding Interview book, the "go-to" resource for interview preparation.

Github: https://github.com/ben-xD/leet

The solutions they give are generally very well explained and the approaches can be ported over to Python, even though the code they give in the print version is Java (which is quite verbose).

The official Python solutions online seems to be a bit lacking, so I've compiled my own after starting to do weekly session with a friend.

Definitely recommend the book, I hope the repo can help anyone going though the questions. Happy to correct any issues/screw-ups :D

Updating old projects vs creating new ones

I have made a project that helps me create an excel spreadsheet for work. We changed an aspect of it so I wrote a new program to reflect that. then we added another type of spreadsheet so I recreated it again to incorporate all three types into one. It is a sloppy mess and it needs to be rewritten with class structure instead of the slew of functions that manages the whole thing. in about 4 months I am moving to a different client so what I have created may not even be applicable for the new client.

This got me thinking if I rewrote the program now to be more pythonic it would be easier to change later. I can try to make it smarter and allow a user to adjust the parameters to format it themselves.

Or I could focus on new projects that are more varied. because I am still relatively new to programming (about a year), does it make more sense for me to try and diversify the types of programs and libraries I work with or get more in depth with the ones I know now and learn how to more efficiently rewrite the code I

Looking for a Technical Co-Founder

Hi everyone, we are searching for a technical founder/CTO who is interested in collaborating on an idea-stage interdisciplinary R&D cloud laboratory for the life sciences. Think Benchling but for all disciplines of life sciences instead of just strictly molecular/biochem, with more workflow-friendly features. If you have experience in a combination of life sciences, coding (be able to build an MVP SaaS solution) and data, then please hit me up and we can talk more!

REMEMBER_COOKIE_DURATION in flask is not working

Hi

I asked [this question](https://stackoverflow.com/questions/63674125/remember-cookie-duration-in-flask-is-not-working) about 23 days ago on StackOverFlow and it didn't get any answers but I really need to fix this on my application.

In the last 23 days I tried other options but nothing works!

views or serializers (Django rest framework). Need help in approach to create a json

im having doubts in what approach i have to follow.

I need to fetch data from multiple models. Do filterings & loop on it and cross check and do calculations from different model data and finally present a json with only the required data for the front end.

Is it possible to do all this via serializers?
Can i pass a list(queryset), loop on it and for each element get data from other models etc.
If yes how do i go about it?
The tutorials are mainly limited to creating fields with serializers or using a meta modal.

Or is views.py the best resort since i'll be more in control with what i can fetch and write, plus end up writing a custom dictionary to output as a json.

Why '&' changes to '&amp' when it gets to frontend? (FLASK-REACT)

I am working on a project with Flask backend and React frontend.

I send data like this

`auth_url = '`[`https://abc.com/tr/authorize?client_id=abc&response_type=code&`](https://accounts.spotify.com/tr/authorize?client_id=a2a038c0cf9f4fb08c36873347d16858&response_type=code&redirect_uri=http:%2F%2F127.0.0.1:5000&scope=playlist-modify-private%20user-read-currently-playing&show_dialog=True)`'`

`return render_template('index.html', auth_url=auth_url, page_name='sign_in')`

When I call this url from React, it changes '&' to '&amp', why it does it make this change.

I did some googling most of the responses says it is due to security reasons.

What is the correct way to create Virtual Environment for a project.

I 've seen several ways to create "Virtual Environment" in tutorials. Can someone tell me what the correct way is or better way. I'm pretty new to Django and Web-Dev, and my first Django tutorial was using this command: python -m venv project_env (new environment name). This works without any issue, but I would like to know if this is proper way. Any help will be greatly appreciated. Thank you.

Automated My Job for the First Time

So this just happened today. I've been learning Python on and off for a long time. I had to take a couple of classes for my undergrad a couple years back, and after that, I never really needed to apply it in my job.

Fast forward to today, my manager was complaining about how many requests for test data the business team was giving him. He tasked me with helping him generate the data using Excel and advanced SQL logic.

I decided to dust off my rusty Python scripting knowledge and created a script that automated the entire process. It took many hours, a lot of googling and 2 mugs of coffee, but I accomplished what I set out to do. My script was able to generate nearly 5000 queries in less than a minute.

Needless to say, my boss was impressed by my initiative, and I've found out first hand how useful knowing Python is. I want to thank this subreddit for being so supportive and always promoting new learning resources. Automate the Boring Stuff is a gold mine of info and I am more motivated than ever before to expand my skills and knowledge!

Pytest API endpoints that do Sqlite DB CRUD

I have a simple page that has a couple routes to do CURD into a SQLITE3 database. That's working fine. But I need to add tests with Pytest to verify their functionality.

Ideally I need to create a new database and somehow make each test use the endpoints in my website but instead of adding and delete data into the normal db, they should use the db created for testing purposes.

After tests conclude this database gets destroyed, in fact each test should spin it's own database so they are all isolated.

I know about fixtures and that I can create a new db and pass it to the tests but I don't know how to make the endpoints to point to this new database only while testing. If anybody have any ideas or point me in the right direction it'd be appreciated.

Dyno reset in heroku deleting SQLAlchemy db

Hi guys, I am a beginner in FLASK and deployed a basic CRUD application on heroku. But what I noticed was after every 2-3 hrs the data entered after deployment gets deleted. I am assuming this is because of the Dyno getting reset.


I am using Flask, SQLite, gunicorn.


Can anyone pls help me out with this and what I should do.

Thanks in advance ❤️

Flask with ReactJS form library - React Bare Forms

If you're using React on your Flask projects either as a front in your flask views or as a separate single page app, then take a look at React Bare forms [https://github.com/joegasewicz/react-bare-forms](https://github.com/joegasewicz/react-bare-forms)

It's designed to be the easiest form library to use in the world for ReactJS.

I would be really grateful for any feedback and your thoughts on the project!

Thanks
