If Then

This function creates a new column based on the conditions provided in the conditions argument.

Output values should be of the same type, since they are constructing one new column.

A default value for the new column should be set, as should the output column name.

Parameters

Name	Type	Description	Is Optional
conditions	conditional_list	A nested list. In each inner list the first element would be the condition to check, and the second the value with which to fill.
default	mixed_value	The default value with which to fill the new column. Please enclose fixed strings in quotes inside of the argument (e.g., below)
alias	string	The name of the output column in the new dataset.

Example

ds = rasgo.get.dataset(id)

ds2 = ds.if_then(conditions=[["DS_WEATHER_ICON like '%cloudy%'", 1]],
      default=2,
      alias="CLOUDY_WEATHER_FLAG")
ds2.preview()
