How to reference the current time in pyscript

[willenic]

Hello,

Forgive my ignorance, I've gone from never having used home assistant to stumbling around python in the last year.

Objective

So I am combining the weather forecast and my 1/2 hourly variable electricity rates to compare to a temperature:efficiency curve to determine when the most cost effective time to run my hot water cycle on my heat pump is.

I have the code running correctly in VS Code and after wrapping the requests.get calls in a task executor I can retrieve the data I need from the 2 api calls in a hass pyscript jupyter notebook. Hooray.

However I want to filter out historical data that is returned, I can't put my heat pump on in the past!

Packages

I import the following packages

import requests
import argparse  
import time  
import sys  
import logging as log  
import pandas as pd  
import csv  
import datetime  
from datetime import timedelta

Problem Code

The first line below is where I am falling over.

today=task.executor(datetime.datetime.now(rates.valid_from[0].tzinfo))

which works fine as below in Visual Studio Code/Python 3 notebook

today=datetime.datetime.now(rates.valid_from[0].tzinfo)
futurerates=rates.loc[rates['valid_from']>=today]

I then use the variable today to filter out data from the past and do other stuff with pandas dataframes

Returning the following error frpm jupyter hass pyscript notebook

Exception in <jupyter_0> line 14: today=task.executor(datetime.datetime.now(rates.valid_from[0].tzinfo)) ^ TypeError: function 2024-11-28 19:34:50.998470+00:00 is not callable by task.executor

Any pointers gratefully appreciated, thanks.
