Next programming language after Python?

Hi all,

I've been learning/working with Python for over a year now. Python was my first programming language and I feel comfortable saying I've got an intermediate level when working with it: I use it daily at my job (research institute), automating data analysis and figuring out new ways to look at our data. I've also done a bit of GUI development with PyQt5 so I can share my tools with my colleagues in a more intuitive fashion.

The thing is, I sorta want to learn a second programming language to complement my skills, but I don't really know which to pick. Does anyone have a good suggestion? Some points to consider:

* I don't have much interest in web development, so JavaScript and PHP are off the table, at least for now.
* Java... well I've looked at it and it seems interesting, but apart from the fact that it's easier to port anywhere due to the JVM it kinda feels the same as Python? Not sure I will gain that much from learning it.
* I've considered learning SQL and databases in general, and I'm sure that I'll learn about them at some point in the future, but since it's more of a

Python decorators explanation for absolute beginners

Hi, everyone!


I have made a video about decorators concept:
\- how to write them
\- how to use

​

I'm reviewing three versions of decorators:

\- simple decorator for a function without arguments

\- a decorator for a function that takes some arguments

\- and a decorator that takes arguments itself for a function that has arguments (like the Flask's route())

Thanks for watching.

I made a Telegram bot you can send messages to, from the console, and get responses back

This is a small project I've been working on. It's a Telegram bot that listens for JSON POSTs on a local port, and forwards the messages to you in Telegram. The coolest feature is that you can send questions, and it will render buttons in Telegram you can click, and receive the response through the JSON API.

I'm using it to monitor my machine learning stuff, i.e., long-running processes that periodically push me the info on current performance. It would be awesome to get feedback on this, especially on interesting features to add. My original vision was to have something on Telegram feeding me with things happening on my servers, and that I could quickly tap something in Telegram to restart a broken process or kill or run something off. This is just a start, but it needs "clients", i.e., ways for people to push messages without having to `curl` or `request` it. All ideas are welcome.

How to get column SUM/AVG calculated

Hey guys,

​

So I wanted to add up some numbers from the column, after doing some filtering. Here what I was able to come up with using info found online. But something is wrong...

seller_received_sum = query.with_entities(func.sum(Testimonials.received).label('sum')).filter(Testimonials.seller == seller) or '<no-data>'

this returns me "<class 'flask\_sqlalchemy.BaseQuery'> SELECT sum(testimonials.received) AS sum

FROM testimonials".

&#x200B;

Some posts online suggested using '.scalar()' on the end of the query, but that returns me error too.

&#x200B;

What does label('sum' is)?

What scalar() stands for?

What's wrong here?

[HELP] Django Rest Framework and Social Authentication

Hi! I started learning the Django framework 2 weeks back and it's been going great overall. However, now I'm stuck at an issue and don't know what the best approach is. I started working with the django rest framework and it was fairly straighforward until I came across having social app authentication. Im working with the django-rest-auth framework which uses allauth for social app authentication. But I have no idea what to do for authenticating my app with this and there aren't a lot of good resources that I am able to figure out. i am a complete novice with regards to the whole authentication scenario and would be immensely grateful in anyone could help me out on what to do. Thank you all in advance.

Flask and Celery for my Rasberry Pi 3 Temperature Logger

To learn a bit more about using Celery and RabbitMQ with Flask, I built a little temperature logging station with a Raspberry Pi 3 + DS18B20 one-wire temperature sensor. Celery + celery beat + rabbitmq are definitely overkill for what I wanted, but it was fun a fun way to learn more about them!

The goal was to have a rest endpoint to get the temperature (Flask) and a periodic task to log the current temp reading to a DB (Celery, celery-beat, RabbitMQ, SQL-Alchemy) that I can consume with Grafana or my own front-end to observe temperature change over time in my daughter's nursery.

[Beginner] [Postgres Query] Filter data for a given day (timezone aware datetime) from postgres directly

I want to filter all data for the following day (which is timezone aware).

**Assumptions:**

* server data is in a specific timezone
* client query is coming from different timezone

**My current approach is:**

date = received_date_timezone_aware # any time of that day
lower = date.replace(hour=0,minute=0,second=0)
upper = lower + datetime.timedelta(day=1)
data = Model.objects.filter(date__gte=lower, date__lt=upper)

**Question**

Is there a direct solution to this using django orm or raw query?

I wanted to know if there is a better alternative which can save me a few lines of code of manipulating the datetime stuffs.

Re-Apply Migrations?

I am using django-cookiecutter and want to know how to run all the migrations again if I want to drop the database? Is there a way or would I have to start from scratch? I would assume there is a way since it would have to run when I move it to Production?

[AF] why am i all of a sudden getting this error? Method Not Allowed The method is not allowed for the requested URL.

Hi all,

I am working on two machines. Mac and Linux. I work on linux during the day, do all my work, head home at night and continue on mac.

I use docker-compose to allow this to happen and I've had little to no troubles all this time.

I finalised another conversion script yesterday on the mac, works a treat. CSV files upload,get converted, life is good. I've made many of these scripts using my workflow.

This morning though I've loaded the same script on the linux machine and am getting `Method Not Allowed. The method is not allowed for the requested URL.`

I have never had this before. I'm simply using:

<form method=POST enctype=multipart/form-data action='convertData'>
<input type='file' name='file' class='UCSV_FileInput'></input>
<button type='submit' value='Upload'>Submit</button>
</form>

and on my views.py I'm doing this kind of thing:

@myroute.route('/convertData', methods=['GET', 'POST'])
def convertData():
if request.method == 'POST':
# all the upload stuff is here

I literally have dozens of these,
