I have a python recipe in my scenario working with a local variable.

I have succesfully executed my scenario within the webapp but :

How can I change the local variable from the webapp's code (in the Python back-end) ?

    Hi @Redouxne
    ,

    Are you using a scenario variable or a project variable? Indeed, for scenario variables, it's only possible to set them from within the context of a scenario.

    So, if you want to set a variable that will be used in a scenario but set it from a Webapp, you'll probably want to use a project variable instead. You can see the following code example for how to set a variable from the Python API, which can be run in the Python backend.

    import dataiku 
    client = dataiku.api_client()
    project = client.get_default_project()
    
    variables = project.get_variables()
    variables['standard']['some_variable'] = 'some_value'    
    project.set_variables(variables)
    


    Then, from your scenario you can obtain this variable in a Python step:

    import dataiku 
    client = dataiku.api_client()
    project = client.get_default_project()
    
    variables = project.get_variables()
    some_variable_value = variables['standard']['some_variable']


    Let me know if this approach doesn't work for you!

    Thank you,

    Hi Sarina,

    Thank you ! At first glance it seems to work, I have another question, do you know how to know when the scenario ended and get the information in my Python back-end ?

    Thank you again,
