Updating a variable from a dataset

akember182

Hello I have a dataset with only 1 row (but will change depending on other inputs) and I want to use it to update a global variable. I know I can use a python function in a scenario for this but can't quite work it out.

I have a dataset (my_dataset) that looks like this

Code. Year

122. 2021

I want to extract the 2021 figure and save it as a variable.

I know I can use code in a scenario along these lines

import dataiku

from dataiku.scenario import Scenario
scenario = Scenario()

df_data=dataiku.Dataset("my_dataset").get_dataframe(infer_with_pandas=False)

df_data = df_data['Year']

Scenario().set_project_variables("year_variable"=list(df_data)[0])

But I can't quite seem to get it working, any advice?

Hi @akember182
,

If you want to set a global variable, you'll need to use the set_global_variables method: https://developer.dataiku.com/latest/api-reference/python/scenarios-inside.html#dataiku.scenario.Scenario.set_global_variables

Please try the following:

scenario.set_global_variables(year_variable=list(df_data)[0])

Please let us know if you have any questions.

Thanks!
