sort subfunction

Logger: custom_components.pyscript.file.wall_box_start.get_new_price

Exception in <file.wall_box_start.get_new_price> line 22: daten.sort(key=sort_price) ^ TypeError: '<' not supported between instances of 'coroutine' and 'coroutine'

@service

    def sort_price(x):
        return x["price"]

   # snipp
   daten = [{'date': '2025-07-15T05:00:00.000Z', 'price': 29.36}, {'date': '2025-07-15T06:00:00.000Z', 'price': 28.58}] 
   daten.sort(key=sort_price)

and

def sort_price(x):
        return x["price"]

@service
def get_new_price():
     # snipp
     daten.sort(key=sort_price)

also fails

...

so how to do sub functions ?

bonus: how to check debug of integration ist on / off ?

lambda works fine:

@service
def get_new_price(trigger_type=None, var_name=None, value=None, old_value=None, context=None, **kwargs):
    daten = [
        {'date': '2025-07-15T05:00:00.000Z', 'price': 29.36},
        {'date': '2025-07-15T06:00:00.000Z', 'price': 28.58}
    ]

    result = sorted(daten, key=lambda x: x['price'], reverse=False)
    log.debug(f"{__name__}:\n{str_.__class__.__name__} {str_}")

The issue is that all functions in pyscript are async. Python's list sort() function requires key to be a regular function. You can accomplish that via a lambda (as @ALERTua did), or by adding @pyscript_compile as a decorator on your sort_price() function. See the 3rd bullet in this section of the docs.
