How to create virtual environment in python in VS code?

Question

Python

Recently I started to master python, I am learning how to create a bot in a telegram using this guide https://habr.com/ru/post/495036/

As I understand it, after the third line from the top, the same environment should be created and in the console it will also always be in the beginning the name ("venv" as in the screenshot), but it doesn't work out for me. I
thought that everything might be ok, I'm moving on. Flask is installed, everything is fine
Next comes this
And I couldn't go any further, because when I type (venv)$ export FLASK_APP=app.py, an error occurs: export : The name "export" is not recognized as the name of a cmdlet, function, script file or running program. Check the spelling of the name
and the presence and correctness of the path, then try again.
string:1 character:1
+ export FLASK_APP=app.py +
~~~~~~
+ CategoryInfo : ObjectNotFound: (export:String) [], CommandNotFoundException
+ FullyQualifiedErrorId : CommandNotFoundException

for some reason it doesn't work for you

Answer 1

You can add an app.run() line at the end of the code and run the code like normal .py code.

Answer 2

Judging by the error, you are executing the code in powershell on windows, while export is a command for Linux.
In Windows, the analogue will be SET.
In fact, I would start with something simple. Virtual environments, ngrok, webhooks. If you have just started learning, it is better to start with the basics of the language. Next, try to create a bot without a webhook, using some library, telebot will be easier . Next, you can already connect it with Flask.
