Linux/Python3/Django/MySQL/Nginx/Apache working environment setup?

Question

PHP

Hello.
I am a beginner Python programmer, and recently finished Python and am starting to learn Django.
And I came across such a question as how to set up a working environment.
If you have ever had such a question, how did you solve this problem.
If possible, give the path (directions).
What should I read.
There is still a question I understand that Nginx, Apache web servers.
and here are wsgi and uwsgi, Gunicorn, etc. Why are they needed.

Answer 1

if you are parsing json, first look at what conclusion it makes on an elementary example. just do print_f($profileJson); and you will see that the variable (array) $_SESSION does not exist. I hope I understand your problem correctly

Answer 2

Everyone adjusts the working environment for himself, as he likes. There are no ready-made recipes here, and no complicated science either. I'm using PyCharm with the IdeaVim plugin. There is no better PyCharm IDE for Python. It may be overkill for a beginner, however, but when you work for the result, and do not study, then PyCharm allows you to save a lot of time.
A beginner should learn, for example, vim, and edit files for the first time in it. Why vim - because it's comfortable when you know how to use it, doesn't cause carpal tunnel syndrome (after switching from Emacs to vim, I forgot about the pain in my wrists), and is on every Unix/Linux server.
It is very difficult to answer what to read, because the question is very vague, and the source data is not clear (you are a beginner or an experienced user, for example). Have you read Dive Into Python?
wsgi, gunicorn, etc. needed because Nginx and Apache are servers designed primarily for serving static files: html, css, pictures. They don’t know anything about Python and they don’t know how to call Python scripts (more precisely, Apache can do it with mod_python, but now few people use it).

For production, you need to know what virtualenv and pip
are. Nothing else
. Python has a web server to display on the developer's machine
. Everything else will be needed when you have to install the script on production.
