Fedora 35 : Python and Flask-Mailing on Fedora.

First of all, a Merry Christmas to the users and the Fedora team. Python version 3.10.1 works very well on Fedore 35 and today I tested a packet called: Flask_Mailing.

Flask-Mailing adds SMTP mail sending to your Flask applications., see the Github repo.

Let's start with the installation of this packet with the pip utility.

[mythcat@fedora ~]$ pip install -U flask-mailing

I create a folder named ExempleFlask001:

[mythcat@fedora ~]$ mkdir ExempleFlask001
[mythcat@fedora ~]$ cd ExempleFlask001/
[mythcat@fedora ExempleFlask001]$ vi flask001.py

I created the simplest example to test through the import procedure and then read with the dir function, here is the source code:

from flask import Flask
from flask_mailing import Mail, Message

app = Flask(__name__)
@app.route("/")
def index():
    test = str(dir(Mail))
    return test
if __name__ == "__main__":
    app.run(debug=True)

The result of running the script on the command line:

[mythcat@fedora ExempleFlask001]$ python flask001.py

The browser's response to the script is this:
