Django admin usage

Hi all,

Just wondering how many people use the Django admin site when developing for clients? I have never actually used the admin functionality for a client build, Ive always built the 'admin stuff' myself.

The reason Im asking is I feel I may be missing a trick and have always liked some of the 'out-of-the-box' features bundled with admin but have never taken the time to try and customise the site.

Thanks.

Creating magic functions in IPython

Hi!

I just found out that there is a subreddit for IPython - that's super cool!

Sorry for a duplicated post (I already wrote about this in r/Python and r/learnpython), but I wrote a short series of 3 articles about how to create magic functions in IPython and I thought it might be interesting for some people here. The documentation of IPython is pretty amazing, but I wanted to practice a bit and create some fun little helpers in each part.

So here is what you can find in each part:

* [Part 1](https://switowski.com/python/ipython/2019/02/01/creating-magic-functions-part1.html) \- where I'm explaining what magic functions are and I'm creating a line magic to interpret some simple *Polish notation* math equations.
* [Part 2](https://switowski.com/python/ipython/2019/02/08/creating-magic-functions-part2.html) \- where I'm talking about cell magic (and "line AND cell magic functions") and I'm writing a type checker that will run `mypy` on a block of code (cell).
* [Part 3](https://switowski.com/python/ipython/2019/02/15/creating-magic-functions-part3.html) \- where I'm talking about `Magics classes`, explaining the difference between creating a magic function with a decorator vs writing a class inheriting from `Magics` and finally - I'm writing a type checker (I actually found the type checker from the previous part to be quite useful!) that can check previous commands (in the same

Why does mybinder.org not recognize a requirements.txt file?

I am attempting to load a Jupyter Notebook through mybinder.org. The repository that the Notebook is in includes a `requirements.txt` file with the content

parsl

because the Notebook uses the `parsl` library.

When I load the notebook and import the library, execution stops with the error

ModuleNotFoundError: No module named 'parsl'

The `requirements.txt` file is _right there_. I have no idea what else to do to get mybinder.org to load the module. What am I missing?

text adventures

im a fan of using standard libraries as to make it as transferrable to each interpreter as possible lol (looking into making a game that clears the screen quickly as to make an old roguelike but even thats far off for me.

Anyway have any experience/tips converting a Flask app using Jinja templating to React?

I have a Flask app that heavily used Jinja templating. However, the issue that I am facing right now is that the app is a static webpage and I want to move over to a SPA in React. So the plan is get rid of all the jinja templating and convert all the jinja features I was using to React features. Does anyone here have any experience dealing with this transition?

Image Pixelator using Python

This is my first post so go easy on me lol.

I made a naive algorithm which pixelates a given image by calculating the average pixel value using PIL and opencv.It is very slow(duh!), took around 10-15 sec to process a 4k image.Please try it out and give me suggestions to do it better or faster.[https://github.com/k4rth33k/code\_bunker/blob/master/pixel.py](https://github.com/k4rth33k/code_bunker/blob/master/pixel.py)

DRF Alternatives.

Hey there everyone. I've gotten quite used to the DRF + Front end framework (Vue) workflow over the past few months, and it's made me realize just how strong Django can be as a back end only solution. For anyone with more diverse experience, what are some alternatives you guys have used for building out DB's / API's that don't involve Django? Specifically in the JS world. Do they compare?
