Depending on how much JS you need to inject, you could consider using .format() on a js as a string and replace the values that way 🤷‍♂

So you skip all the python > html > js dance

Hello, I was using Flask to build HTML with Jinja and send it to the user's browser like this: 🐍

return render_template("index.html", user=user_data, money=users_db.money_value,)

for this case, user and money values are inserted into the Flask template on the fly coming from Python3.

However, when I try to send the
/static/js/filename.js
file, it is served automatically. As a result, I have to hardcode each variable in the .js file, since Flask automatically sends the .js file to the user without dynamic context. 😢

var UUID_RE =-Za-z0-9_-]+)/;

var SHORT_RE = ([A-Za-z0-9_-]+)/i;
var HOOK_RE = -9a-f]{4}-[0-9a-f]{12})/i;

var DEFAULT_PROXY = "/api/endpoint/somethign?url=";
var HOOK_API = "/video/web/somethign";

That's not helpful. And a reason for a warning from different perspectives.

What, specifically, is the problem?

Python

defined a simple function, def, a list, and a dictionary — in every case it printed the value correctly, because Python's print() works on any object type by converting it to its string representation internally, so the function doesn't care what kind of data x holds 🐍. However, when I called show() with no arguments at all, Python raised a TypeError: show() missing 1 required positional argument: 'x', and when I called it with two arguments like show("hello", "world"), it raised TypeError: show() takes 1 positional argument but 2 were given — this happens because while Python is flexible about the type of data a function accepts, it strictly enforces the number of arguments based on the function's signature, and since x has no default value, exactly one argument must be supplied, no more and no less; if you wanted to allow a flexible number of arguments, you'd need to use a default value like def show(x=None): or a variadic form like def show(*args): instead 🛠️.

If you want to host something yourself you'll have to learn these concepts

Python

You'd use tmux for development and systemd to host a production app.

I have a question about passing data from Python to HTML hidden fields. When inserting values from Python into my HTML hidden fields, I sometimes need to pass the correct data type. For example, if I have a variable like money = float, I need to send it, but HTML stores it as a string, so JavaScript will try to convert it into an int and use it.

Additionally, consider this regular expression:

var UUID_RE = /^[0-9a-f]{8}-[0-9a-f]{4}-[0-9a-f]{4}-[0-9a-f]{4}-[0-9a-f]{12}$/i;

In this case, how should I take it from Python's backend and pass it into JavaScript, given that this is not a simple string type in JS? Also, if I want to pass this via a Python context_processor, what should the data type be in Pydantic's pydantic-settings?

You pass it to HTML document and grab its value with JS 🤷‍♂

Can anyone help me with this


At the Python interactive prompt, write a function that prints its single arguunent to
the screen and call it interactively, passing a variety of object types: string, integer, List,
dictionary. Then try calling it without passing any argument: What happens? What happens
when you pass two arguments?

Sure I can help Send me the code you're trying to run and tell me what happens when you run it Also let me know which Python version you're using

Python

Please provide a full explanation including all the details that you consider relevant. Your statement is too broad and there is no clear way to answer you, you have to explain:

- what you're doing
- what you're expecting
- what you're using
- where you're running the script
- what Python version you're using
- what packages and their versions you're using
- and the most important thing: show the code YOU wrote (read rule 5️⃣ for that)

and more details, that way your chances to get help will increase.

Look up how to create a systemd service and then use that with your Python code

Python

18 September 2026 18:05

tmux is (basically) designed to let you keep a shell session even if you close your terminal. You can then open another terminal and reattach to the same session (because it carries on running even if you're not attached to it). This works nicely for your uv run use case, for dev work.

Python

18 September 2026 18:02

so there is two type of things i need to setup, to keep running 1 things always correctly?
what what these, tmux , systemd.
thought i never used this and knew nothing about this, are you saying this to use to host real python app ?
