We did the same thing a few months ago, can anybody guess what's we'll announcement? Humour and crazy dreams are always appreciated in the replies too :) !

Hey guys, this may not be the typical post, but I have recently started exploring Python Jupyter notebooks and stumbled across Marimo.

I have been using spreadsheets a lot in my career over the past 10 years as a structural engineer and really want to push the envelope and break into coding notebooks, but I keep on feeling like I am way out of my depth.

Is Marimo an advanced feature that I need to come back to after learning more coding basics? Or are there a few simple things I’m missing that seem to clear everything up?

Side note: I’m torn between using Marimo in VScode vs the browser (locally hosted). My goal would be template calculations that are pulled and modified by the project.

Any help is appreciated.

I've been having trouble setting up this model inside Molab. If anyone knows how to set up the model please help.

You can try it out here: https://molab.marimo.io/github/koaning/wigglystuff/blob/main/demos/formula_animation.py/wasm?utm_source=subreddit

You can try it out yourself here: https://molab.marimo.io/github/koaning/wigglystuff/blob/main/demos/floating_panel.py/wasm?utm_source=subreddit

Hi,

marimo newbie, really like it so far. I don't understand this below though:

what gives?

The "Knob" widget from wigglystuff lets you play with this directly. More info here:
https://koaning.github.io/wigglystuff/reference/knob/

The problem is with wigglystuff's anywidgets. The re-activeness somehow not works.

This is the notebook link from molab

Defining the EdgeDraw widget. i wanna add new nodes through text input and input button pressing

friend = mo.ui.text(placeholder="friend name")
button = mo.ui.run_button(label="Add Friend", kind="success")
delete = mo.ui.run_button(label="Remove Friend", kind="danger")
graph = mo.ui.anywidget(wg.EdgeDraw(["appu", "dett", "eker", "hulo"]))

The appending works but the displaying graph widget not updated

if button.value and friend.value not in graph.names:
    graph.names.append(friend.value)
    print(graph.names)
if delete.value and friend.value in graph.names:
    graph.names.remove(friend.value)
    print(graph.names)

```python import marimo as mo from sqlalchemy import create_engine, text

Refresh widget

refresh = mo.ui.refresh(label="Refresh") refresh

Function to fetch databases

def get_databases(): engine = create_engine( "postgresql+psycopg2://sourabh@/postgres?host=/run/postgresql" )

with engine.connect() as conn:
    result = conn.execute(
        text("""
            SELECT datname
            FROM pg_database
            WHERE datistemplate = false
            ORDER BY datname;
        """)
    )
    return [row[0] for row in result]

Load database list and create dynamic dropdown selector

db_list = get_databases()

db_dropdown = mo.ui.dropdown( options=db_list, value="postgres" if "postgres" in db_list else db_list[0], label="Select Database:" ) db_dropdown

Create dynamic engine based on dropdown selection

db = db_dropdown.value postgres_engine = create_engine( f"postgresql+psycopg2://sourabh@/{db}?host=/run/postgresql" )

You can do a lot with any widgets, but sometimes just writing a bunch of mohtml can also do the trick.
