Having trouble getting flask to run.

Hi

I'm having trouble getting Flask to work. Here's some background and where the problem is:

\- I'm new to python but I've programmed in other langagues.

\- I'm on a Windows 10 Pro laptop.

\-- I'm following this youtube tutorial: "Python for Web Development – Crash Course [API, SQL Databases, Virtual Environment, Flask, Django\]"

Everything has been going fine and I was excited to get into the web app section. At the 52 minute mark, he starts the section labeled "Flask Setup". Here's what I did:

\- Following his instructions, I installed Flask using:

pip install flask

\- It installed without errors.

\- Next he says to create a virtual enviornment for a new project. So I did the following:

python -m venv webBookmarks

("webBookmarks" is the name of hte project I want to work on.)

\- I actived it using:

webBookmarks\\scripts\\activate

\- I'm now in the 'webBookmarks' VM as shown in the format of the command prompt:

(webBookmarks) c:\\Clem\\python\\Virtual environments\\webBookmarks>

\- Next, he says to use this command:

(webBookmarks) c:\\Clem\\python\\Virtual environments\\webBookmarks>FLASK_APP=app.py

\- When I issue that command, I get the following error:

* 'FLASK_APP' is not recognized as an internal or external command, operable program or

Creating a site like Alltrails.com in Django (Django beginner question)

I want to create something similar to Alltrails.com like this page https://www.alltrails.com/en-gb/explore/england/staffordshire/newcastle-under-lyme?b\_tl\_lat=55.78716611610855&b\_tl\_lng=-9.493297338892177&b\_br\_lat=49.881806552115165&b\_br\_lng=4.888657338893637&mobileMap=true

Something where users around the world can add routes on a world map with photos and a description, which others users can search, view and add comments on.

I was just curious if it's possible in Django. Can I use Django + Tailwinds + HMTX + Openstreetmaps (+leafletjs) to achieve something similar?

Are there any specific tutorials or resources that might help? (i've learnt the basic beginner Django basics)

Zillow scraper made pure in Python

Hello everyone., on today new scraper I created the python version for the zillow scraper.

https://github.com/johnbalvin/pyzill

What My Project Does

The library will get zillow listings and details.
I didn't created a defined structured like on the Go version just because it's not as easy to maintain this kind of projects on python like on Go.
It is made on pure python with HTTP requests, so no selenium, puppeteer, playwright etc. or none of those automation libraries that I hate.


Target Audience

This project target could be real state agents probably, so lets say you want to track the real price history of properties around an area, you can use it track it


Comparison 

There are libraries similar outhere but they look outdated, most of the time, scraping projects need to ne on constant maintance due to changed on the page or api



pip install pyzill

Let me know what ou think, thanks

about me:
I'm full stack developer specialized on web scraping and backend, with 6-7 years of experience

Py2wasm: A Python to Wasm compiler 3x faster than pyiodide

Take the excellent nuitka, compile python code to C, turn it into web assembly, and you got Python in the browser, without the usual runtime overhead:
https://wasmer.io/posts/py2wasm-a-python-to-wasm-compiler

While the doc states you can get this effect by doing:

pip install py2wasm
py2wasm myprogram.py -o myprogram.wasm
wasmer run myprogram.wasm

You still need the wasmer WASM runtime (curl https://get.wasmer.io -sSfL | sh for Unix users, iwr https://win.wasmer.io -useb | iex for Windows user with Powershell), however. But more than that, since you need nuikta, it means you need a C compiler installed. While in Ubuntu it's a just an sudo apt install build-essential, it will require a bit more work on Windows and Mac.

I am terrible at this but trying to learn.....hosting?

I created a flask app that I would like to direct people too from my wordpress blog, which i am hosting on Bluehost. While there is supposedly a way to get my flask app hosted on bluehost, it seems like a major task.

I have heard there are simpler hosting methods. Can someone recommend one?

I finally got my flask app running locally as I want it, just need somewhere to host it so i can point to the site from my blog. Any suggestions that can handle decent traffic? Free is great, cheap is fine.

Any help is appreciated. If there is a tutorial made for idiots please recommend it. I have never deployed anything like this before.

Created Netlify DNS Manager: CLI Tool for uploading zone Files to Netlify or exporting Netlify DNS

What My Project Does?

Command-line tool to simplify the management of DNS records for domains hosted on Netlify, whether you want to migrate to Netlify or migrate away from Netlify.
1. Import Zone File from Godaddy, NameCheap or others to Netlify - helpful in migrating nameservers.

2. Export DNS records from Netlify as zonefile to be imported.

Zonefile is a list of all the DNS records for a given domain


Here is the url - https://github.com/sumansaurabh/netlify-dns-manager


Target Audience (e.g., Is it meant for production, just a toy project, etc.)

Anyone who is intended to use Netlify DNS.


Comparison (A brief comparison explaining how it differs from existing alternatives.)

There is no such tool that can help in managing DNS in Netlify - hence I have created it.

Runtime type checking performance

I'm trying to decide whether to use typeguard or stick to assert isinstance in the places where I care. Has anyone done benchmarking testing of the overhead of using type guards "at"typeguard decorator ?

Best way to grade Jupyter-Notebooks?

I recently took a job with a professor, that includes helping with the grading of biweekly assignments. So I basically have now 30 Notebooks that I have to grade. Top of my head I can think of these approaches:

1. Convert to PDF and write into the PDF
2. Duplicate the Notebook and write the comments in extra blocks
3. Create a .txt file with all my note

Does anybody have experience with this and can share their workflow?

findwhere - my first Python package published to PyPi

[PyPi](https://pypi.org/project/find-where/)
[Source](https://github.com/danohn/findwhere)

What My Project Does
find_where is a Python package that provides a function to find values in dictionaries where a specified key matches a given value, similar to filtering in SQL.

Target Audience
This is my first attempt at creating a Python package so I would describe this as a toy project at this stage but am definitely looking for feedback from the wider community.

Comparison
I mainly wrote this package because I kept on writing the same iterable based code when trying to find a value, given a key:

data = {
"people":
{"first_name": "John", "last_name": "Smith", "age": 25},
{"first_name": "Alice", "last_name": "Jones", "age": 32},

}

firstname = None

for result in data["people"]:
if result["age"] == 32:
firstname = result"first_name"
break

print(firstname)


When using find\where, you can

pwdgen v2 -a simple password generator

https://github.com/RadoTheProgrammer/pwdgen

# What my project does

My project generate simple, strong, memorable and easy-to-type passwords.

The system is simple: it generate 2 pronounceable words separated by a special char, with a number at start or end.

I tried creating a password generator that combines simplicity, security, memorability, and ease of type.

This should be secure enough because it can generate 4e15 possibilities of passwords and uses the secrets module.

# Target audience

For anyone who need to have passwords easily.

# Comparison

Most passwords manager generate completely passwords with completely random characters that aren't very easy to memorize or tape.

Examples include Dashlane, Norton, Avast.

Or other like Bitwarden generate passwords that are not really fast-to-type.

The mine generate sth like 7Xy-Bonuwucete 0Qubyby+Pomafy , or 7Zuxogu:Lebuwo .

# Usage

You can install it with pip install pwd-generator and use the cli version:

pwdgen

To use it in a python code

import pwdgen
print(pwdgen.generate())

# Changes from last post

I already made another post for this, but this was not well received because my code use the random module.

I updated it to use the secrets module.
