jinja2.exceptions.TemplateNotFound

[DevBeginner1]

Hi.

I am discovering flask by following a tutorial on the web site : https://www.geeksforgeeks.org/flask-http-method/
I am trying to repeate the exercise but when I try to open the server after I have launched the Python script, it doesn't work. And I don't understand as I have created the "templates" directory, and put there the .html files.
Here are screenshots about my project and the issue.

Thanks for the help.

try to move the files
.gitignore
app.py

out of the venv directory to the same directory level as the templates directory

Then adjust your run/execution command accordingly
E:\Python_Web_dev\blog2\venv\Scripts\python.exe E:\Python_Web_dev\blog2\app.py
