E2430 for-in statement cannot operate on collection type '%s' (Delphi) Go Up to Error and Warning Messages (Delphi) A for-in statement can only operate on the following collection types: Primitive types that the compiler recognizes, such as arrays, sets or strings Types that implement IEnumerable Types that implement the GetEnumerator pattern as documented in the Delphi Language Guide Ensure that the specified type meets these requirements.To make the example to work, replace with this line:

When one reaches the chapter — "Processing requests", there will be problems with Abyss Web Server, the settings made according to the official guide will not help: Adding Python Support.
All examples from the book work when leaving the page ".html" to ".py" page, parameters are passed and everything is displayed.
However, then suddenly everything stops working, even those examples that just worked, when trying to pass something from ".html" to ".py", Abyss Web Server gives the 500 error.
The record in the log: "AttributeError: partially initialized module 'cgi' has no attribute 'FieldStorage' (most likely due to a circular import)."
Turtle graphics is a popular way for introducing programming to kids. It was part of the original Logo programming language developed by Wally Feurzig and Seymour Papert in 1966.
from turtle import *
color('purple', 'cyan')
begin_fill()
while True:
forward(200)
left(170)
if abs(pos()) < 1:
break
end_fill()
done()
The example was found in the book "Head First Python, 2nd Edition" by Paul Barry, released November 2016, Publisher(s): O'Reilly Media, Inc.
import flask
print(flask.__version__)
Second way: one command in Command line:
pip show flask
The installed Flask version is uptodate - 3.0.3
from platform import python_version
python_version()
Second way: one command in Command line again:
python -V
The installed Python version is uptodate too - 3.12.3
from flask import Flask
from flask import render_template, request
The method request.user_agent.browser returns nothing.
from ua_parser import user_agent_parser
web_detail = str(request.user_agent)
user_browser = user_agent_parser.ParseUserAgent(web_detail)
browser = user_browser['family']
or briefer in single code line
user_agent_parser.Parse(request.user_agent.string)['user_agent']['family']
I digress a little from the main trend of this note and give a method that receives all the User Agent:
request.headers.get("user-agent")
from markupsafe import escape instead of from flask import escape.
Jinja is a dependency of Flask and Flask V1.X.X uses the escape module from Jinja, however support for the escape module was dropped in newer versions of Jinja.
Markup and escape should be imported from MarkupSafe.
from flask import escape was found on the page in the article It’s Time to Escape (Your Data) in the book "Head First Python, 2nd Edition" by Paul Barry, released November 2016, Publisher(s): O'Reilly Media, Inc.

A favicon (/ˈfæv.ɪˌkɒn/; short for favorite icon), also known as a shortcut icon, website icon, tab icon, URL icon, or bookmark icon, is a file containing one or more small icons associated with a particular website or web page.
In March 1999, Microsoft released Internet Explorer 5, which supported favicons for the first time. Originally, the favicon was a file called favicon.ico placed in the root directory of a website. It was used in Internet Explorer's favorites (bookmarks) and next to the URL in the address bar if the page was bookmarked.
Taken from Wikipedia
To add an icon to the site one must place an ico format file named favicon.ico in the root directory of the site.
But the uniGUI site does not have a root directory. Placing favicon.ico in the module directory does nothing.
This problem can be solved in various ways.
The Viber Analyzer on uniGui project and Embarcadero Delphi 10.4.1 Sydney are used as an example.
The first way is the most obvious.
Since web application is coded in Delphi, one can add an icon to it, like to an ordinary program.
The icon can be set in the Project->Options...->Application->Icons->Application Icon Settings->Icon.
And this icon will be the site icon.
procedure TUniServerModule.UniGUIServerModuleBeforeInit(Sender: TObject);
begin
try
Favicon.LoadFromFile('favicon.ico');
except
end;
end;
procedure TUniServerModule.UniGUIServerModuleBeforeInit(Sender: TObject);
begin
try
TUniGUIServerModule(Sender).Favicon.LoadFromFile('favicon.ico');
except
end;
end;
