How to Start Machine Learning in python in 2021 for free & 100% online

Here's a complete guide to start and improve in machine learning (ML), artificial intelligence (AI) in 2021 without ANY background in the field. I also share my tips on how I stay up-to-date with the latest news and state-of-the-art techniques.

I made a data dashboard web app which you can interactively build by writing python code IN the dashboard. It's available as a python package, and contributors are very welcome! (and I actually need some)

https://github.com/phillipdupuis/dtale-desktop

And here is a quick little demo, since a picture is worth a thousand words and all that jazz:

​

https://reddit.com/link/le6lfm/video/f15q4w5f5xf61/player

You can install it via pip install dtaledesktop, and you can run it by either entering dtaledesktop into a terminal or via python code like import dtale_desktop; dtale_desktop.run(). The visualizations are provided primarily by dtale, an amazing tool for exploring pandas DataFrames.

The motivation is to make it simple for researchers/analysts/etc. to organize their python scripts into a functional dashboard. It allows them to run those scripts and explore the data visually by simply clicking a button. They can edit the code or add new scripts at any time, and results/insights can be shared with peers by simply sending them a link.

If anyone is interested in contributing, as long as you know how to use pandas you're probably qualified. What I'm currently looking for help with is building out a library of 'template' data sources for less python-savvy individuals. An example of this could be a template for loading csv files from a remote server -- the user would click "Add Data Source", they would pick the "Remote CSV Files" template, and then they would just plug in the paths to the files

Outdated Flask extensions

I basically love Flask and its open source culture.

But what I noticed is that some important extensions don't seem to be maintained anymore. For example, flask-restful had its last commit in October last year, and currently 78 issues and 35 pull requests. That looks like that the owners of the repo are not working anymore on this extension. Doesn't that even impose security risks if nobody fixes possible flaws?

I built a URL Shortening Tool which provides Smarter Analytics!

TLDR: Looking for reviews on my first side project: **https://tracer.syscape.live/**

It is a minimal app, which does what it says. Shortens your URL, and provides you with analytics.

Analytics Include:

IP Address
Location of ISP
RAM
OS
Device Brand and Name
Battery Percentage when URL was clicked

Hey guys, so this lockdown, I built a url shortening service using Flask, DynamoDB, AWS SES, Nuxt.js, AWS Amplify and AWS Lambda.

We also provide these analytics on a user friendly dashboard.

I would much appreciate your feedback on the website. We plan to add much more stuff like map based UI for location, etc.

CONFETTI - The way to start a Django project with Docker

I tried to accumulate best practices that I used for a long time in one project. I hope you'll learn something new from this. It's not a template, it's more like 'copy some piece if you need this'. I will add more stuff, e.g. Redis, Celery... If you find it useful)

Don't hessite to make any improvement, pull requests are welcome.

I created a web app that lets you practice trading in the stock market

Address: investick.net

How it works:

You get $500k (virtual cash) and you can start buying and selling stocks and crypto. You can check your performance (day, month, year...) and see how you stack up against others on the leader-board.

​

buying and selling some stocks

​

performance of portfolio and stocks, news about your stocks

​

It's a PWA, which means it's fully responsive and you can "install" it.

It's free without any ads.

​

Tech stack:

Frontend - vue 2, vuetify, chartist for the graphs, gsap for the number transitions. Also vue-cli which is a great tool.

Backend - django, django rest framework.

​

My thoughts about django - overall it's a great framework. I like that it's built in with a great ORM, a user management system and an admin panel. the model system is super easy to work with. My only tiny problem is that I couldn't find a good tutorial/library about how to use session authentication when you have a spa and use django just as a rest api.

​

Ask me anything if something is not clear.

I would love to hear your feedback and ideas on how to improve this :D

how does pewee ORM work with heroku for postgress?

Hi there I use peewee for flask and it works fine, even with postgres locally. But, when I go to heroku there is where I am unsure how to proceed. Do I need to statistically type the postgres heroku info ? I cannot seem to find the answer in heroku, some people recommend this #DATABASE=PostgresqlDatabase('heroku'), but it did not work for me. Again thank you!!

​

​

​

DATABASE = PostgresqlDatabase(

'',

user='',

password='', # Ditto.

host='') # Ditto.

I just used Python to grab the rest of the semester's lecture notes in a discrete math class I'm taking!

I've been programming for a long time, but this is the first time I've used it in my day-to-day life! I realized that the lecture notes for a class I'm taking are listed sequentially as urls, so I figured they might be exposed on the server despite not being posted directly on the website. UrlLib to the rescue!

Here's the link to a tiny GitHub repo if anyone's interested.

How do you mock authentication in flask unit tests (pytest)

How do you guys mock the oauth2 token authentication while writing unit tests in pytest. I have tried pytest-mocks "patch", assigning a simple decorator (which gives back the function itself) to the authentication module and yielding the app. Nothing seems to work, it always goes to the original authentication module when I run the tests. Any ideas?

Kids Python 101 learning materials

Hi Reddit folks,

I have developed free learning materials for young kids (targeting 8+ kids) to learn Python from scratch on https://kidspython.com lately. I put lots of efforts on simplifying the course materials, providing plenty of good examples and sufficient exercises for kids to practice coding. The Web site even provides a Python Playground that supports visualization mode for kids to trace their code execution.

I hope the information is helpful. Please give it a try, and subscribe to our YouTube channel for watching Kids Python 101 videos.

Are Django Templates not enough?

I am learning Django and based on the resources I've covered so far I know that Django can handle frontend with the templates. But most often I read about people preferring Django + a JS frontend framework.

What are some of the limitations of templates that make people prefer working with React, Vue, or Angular?

Better ways to use a csv file in Django

Hello everyone,

I am building a web app in django that relies on a deep learning model. In my backend, I have used pandas to store information about my dataset (my dataset consists of images, the CSV files contain columns such as name, path, and an embedding for the images), and I am using the embedding of these images in Django. However, I would like to know if there is a better way than parsing a CSV file to obtain my information.

​

Thanks in advance!

Django Rest Framework

Using Django Rest framework, ModelSerializer to be exact, I am able to serialize my Django models. However, when I send a get request using postman my data does not return as Json, but as HTML, I’m not sure exactly what I’m missing. Any suggestions?

Short Django Reset Password Tutorial

I published a short video earlier today based on a few requests. People have been asking for a tutorial on how to create reset password functionality with Django.

I use the built in functionality from Django, but I override the templates.

If you want to check it out, you can find it here:

Best ways to increase flask security?

This weekend, I got my first rest api running on heroku. It was a simple POST-GET api for moving data I had stored in a database to a simulation of a frontend interface.

My problem is that the domain branch is incredibly guessable, and it doesn’t take advantage of the random api key I have logged to every user in my database. I haven’t been able to research authentication methods built into flask so any resources on that would be insanely helpful.

My app is built in a way that flask moves json data around, but I want to do it in a way that the user never has to see, with security I don’t have to constantly monitor.

Any and all help is appreciated. Looking for a general-type view of authent on flask.
