current date as default in a widget while scheduling the notebook

[philip]

I have a scheduled a notebook. can I keep current date as default in widget whenever the notebook run and also i need the flexibility to change the widget value to any other date based on the ad hoc run that I do.

second parameter is default value, here is example code:

data = [{"Category": 'Category A', "ID": 1, "Value": 12.40},
        {"Category": 'Category B', "ID": 2, "Value": 30.10},
        {"Category": 'Category C', "ID": 3, "Value": 100.01}
        ]
df = spark.createDataFrame(data)
 
values = [row.ID for row in df.select('ID').collect()]
default_value = str(max(values))
values_str = [str(value) for value in values]
dbutils.widgets.dropdown("ID", default_value, values_str)

So building on the answer of Hubert:

from datetime import date

date_for_widget = date.today()

So if you use date_for_widget as your default value, you are there.

And ofc you can fill this date_for_widget variable with anything you want.

You can even fetch a value from outside databricks, f.e. with Azure Data Factory.
