This is totally unrelated to your earlier question, and (as many things Flask) well documented.

When you look at the exported symbols, there is no route, so if you
expected flask to export route it is not there either.
How is that even possible?
Do i have something wrong in the www.py?
from flask import Flask, route, request, redirect, render_template, url_for,
send_from_directory, debug
app = Flask(__name__)
app.run(debug=True)
There is 2 possibilities here. One is you have a module named route.
Than you do not import it as a name from flask, but as a module.
The other is you are looking for the attribute route from the Flask class.
@app.route("/item/", methods=["GET", "POST"])
This creates a route. The route method is a method of an instance of
Flask (i.e. app), so importing Flask is enough.
Also i use run for this
app.run( host='superhost.gr', port=5000, debug=True )
Yes, that is OK, if DNS contains a host superhost.gr.

Re: Php vs Python gui (tkinter...) for small remote database app

I find that hard to believe given the long list of CVEs I've just had to sort through for even fairly recent versions of PHP. I just can't belive that Python has anywhere close to that many secruity issues. An excellent example. The "concerns" here are "Is this platform safe?" and "Does the supplier/community react promptly to security problems?". In case of PHP indeed the safety of the platform is a worry, however, apparently if there is a problem, action is taken. How does the Tkinter/TCL/TK software or the PyQt/Qt do in that respect? Just looking at the number of CVEs, is that enough? What if one of these stacks has few, but long outstanding security problems? Would that be better or worse than the situation for PHP? As an aside, I do not know the amount of CVEs PHP nor Python is receiving. When I search the NIST CVE database for the word Python I get 43 hits for the last 3 months. None of those are against the language or the CPython interpreter and only 1 against a Standard Library package or module (urllib3). A lot of the others are for web frameworks and extensions for those, as well as Tensorflow. So as you argue, it seems Python does really well as a secure development platform. -- Met vriendelijke groet / Kind regards Menno Hölscher -- https://mail.python.org/mailman/listinfo/python-list
Re: Php vs Python gui (tkinter...) for small remote database app
Op 14-06-2021 om 21:17 schreef Pascal B via Python-list: Hi, I would like to know if for a small app for instance that requires a connection to a remote server database if php is more suitable than Python mainly regarding security. Php requires one port for http and one port for the connection to the database open. If using Python with a tkinter gui, I understand a small app can connect to a database so only one port to the database would need to be accessed/open listening to connection. So I would need to worry less about security if using Python over Php for something small, like a small python app that I give over to users. Am I missing something in this assertion? There is no difference regarding security concerns. In the case of a PHP (or any web app for that matter) you indeed have to worry about the security of the connection to the browser. But, e.g. the access to the database is only in one place, on the server. If you use a Tkinter application, each user will have the access to the database at his/her own machine, causing other worries than connection security. The attack vector may be different, but the worries are no less or more in one of the solutions. First investigate what you need to be afraid of/worried about, do not make a decision on a simple criterion like the number of connections. -- Met vriendelijke groet / Kind regards Menno Hölscher -- https://mail.python.org/mailman/listinfo/python-list
