I am trying to calculate today's date using a calculate field function in Notebooks. In regular python code, I can set the expression type as Arcade and use "Now()" to calculate the date. However, that doesn't seem to work in Notebooks. Below is my calculation and error, any suggestions? I only really care about getting the date, the time isn't as important.
dateCalc = calculate_fields(input_layer=joinedData,
field_name="data_date",
data_type="Date",
expression="Now()")
Output:
