Flask Email Validation - Stop Nonsense Emails

For example, I get some emails that are clearly nonsense like sfdjhkj@kjh.com...

is there no way to mitigate this or some kind of library/algorithm to verify the validity of an email?

Doesn't have to be 100% of the time just in general.

[R] Facebook has released code and pretrained models for Cross-lingual Language Model Pretraining

It's an impressive piece of work that get state-of-the-art results on Cross-lingual Natural Language Inference and unsupervised Machine Translation (even out-performing supervised Machine Translation in some settings).

The model is a cross-lingual implementation of BERT.

Discussion: What to call the "main" app in your Django Project?

I'm starting a new project and it will be a collection of Django Apps with their own functionality (as intended by the Django Framework). However, I usually create a home/base/main app for the landing page, all of the base templates, static files, ... What is the preferred way to call this or handle this?

Following Flask production deployment tutorials, how safe is it to host a small scale webshop using Flask?

I want to host a really small scale webshop - only meant for a Facebook group - on my Raspberry Pi. I've read that I need to properly deploy it for production, which I intend to do.

My plan is to store addresses locally and have PayPal take care of the payments.

How safe/unsafe is this? Is there something I oughta know before I make this?

Error in documentation

Hi,

I am a beginner. I was going through the getting started documentation and found some typos and error.

[https://docs.djangoproject.com/en/2.1/intro/tutorial03/#writing-more-views](https://docs.djangoproject.com/en/2.1/intro/tutorial03/#writing-more-views)

def detail(request, question_id):
return HttpResponse("You're looking at question %s." % question_id)

def results(request, question_id):
response = "You're looking at the results of question %s."
return HttpResponse(response % question_id)

def vote(request, question_id):
return HttpResponse("You're voting on question %s." % question_id)

Gives the following error:

return HttpResponse("You're voting on question %s", % question_id)
SyntaxError: invalid syntax

To solve the problem I performed

*return* HttpResponse("You're voting on question %s", question\_id) #excluded the '%' prefixed to question\_id

​

I am using Linux python3.7 django 2.1.5.

Will the changes be made or should I make an official report on their site?

If so, How should I sent the error to the django team.

How to Make a Desktop GUI Application in Python?

Nowadays Python is one of the most popular programming languages. Specialists value its universality for all types of the tasks. Today, one of the most important qualities is convenience of command execution, but often developers have to write a relatively simple program, the quality criterion of which is an intuitive graphical interface. You have several ways to do this by means of Python. The following development tools are among the most popular:

* [PyQt](https://pypi.org/project/PyQt5/). The widespread Qt library, which implementations are available in various languages. It’s written in C++ and is cross-platform. This library allows the development of applications that have familiar and ordinary appearance in the general sense of this word.
* [Tkinter](https://docs.python.org/3/library/tkinter.html)**.** This tool is often referred to as standard for developing GUI applications in Python, appeared back in the early 90s of the twentieth century. Due to the long history and ease of use, Tkinter has a rather extensive and active community. It’s thanks to it you can find a large number of semi-finished products or publications in the network and get an answer to any question at specialized forums.
* [WxPython](https://wxpython.org)**.** Another descendant of C++, namely WxPython, links the wxWidgets cross-platform library with Python. In some ways, Tkinter and

django-taggit vs PostgreSQL ArrayField - I know the differences, but what are the technical implications

Hey guys.

I'm currently working with django-taggit for my "Tag" fields, because for quick prototyping I just use sqlite. However now I'm almost done and I have to work on a more serious setup. I will be using PostgreSQL as my main production (and dev) database. And I like to use as few external third-party packages as possible. That includes django-taggit. I would like to replace this with a Postgres ArrayField. Since django-taggit uses a `form.save_m2m()` it looks like it just uses a ManyToMany Field. And I understand that also.

But I don't have enough in-depth knowledge. What are the actual technical implications? Are ArrayFields significantly faster? Are there any up/down-sides I'm not seeing for either of the two? Is there even any significant difference between the two?

Thanks so much in advance. I hope this is of interest to others as well.

Looking for some Django buddies

Hello everyone!

I started learning web development last year somewhere around January and I've noticed that more I learn, less people are interested when I talk about web stuff. Lately all I get are headnods and "mhm" replies. It kinda sucks because I really enjoy learning these things and would like to share with someone, but my family and friends have zero interest in this stuff.

I've been following this community for a while now and I can see that there are a lot of skilled people that share the same interest as me, so if there's someone who would like to talk with me from time to time, whether you're a guy or a girl, expert or beginner like me, just let me know! :)

I'm from Slovakia, so I'm looking for someone who's preferably from Europe, can speak English, Slovak or Czech language and is at least 18 years old (since I'm 26 and feel like I don't belong in the teen category anymore)..

I'm using Discord for communication, so just message me your Discord tag and I will add you right away. :D

​

Thank you!

Question about * instead of a line number

Good Afternoon - Really sorry about posting a thread about this but i'm at my wits end here trying to figure this out.

I'm working in Jupyter (new to python) and am simply trying to run any code... at all. I have been unsuccessful. When i put any code in and hit run, an asterisk shows up instead of a line number and Jupyter creates a new line. So i'm expecting \[1\], \[2\], etc and instead i get \[\*\] for any and all types of code i try to run. I haven't been able to run one line of code in Jupyter using either the play button or hotkeys.

Obvi i am a beginner but i've been working with R for a little and wanted to try Python out. Ran across Jupyter from the IBM Coursera program. Anyone know how to fix this? i can't seem to find an answer for this anywhere and its probably something super simple and i'll feel stupid but please help anyone lol......
