Description

Screenshot

In this example, we want to check if the WEEK_OF_YEAR attribute is a Week attribute.

Change the WEEK_OF_YEAR attribute type to nominal, as the string parameter needs to be nominal.

We add a new attribute, that we will call isweek, and write the following formula to fill it:

isWeek($"WEEK_OF_YEAR",False)

We wrote False as we want our results to be displayed in binary form.

As the values of the WEEK_OF_YEAR attribute are not in the formats listed above, the function has returned only 0, which means false, setting the isweek attribute type as integer.
