Hi, I am trying to modify the value of a parameter in python. However, I am getting the following error : "'NoneType' object has no attribute 'append'". What can i do?
this is my code to change the parameter "Test_Parameter" value to 2000 :
import olca client = olca.Client(8080)
setup = olca.CalculationSetup()
redef = olca.ParameterRedef()
redef.name = 'Test_Parameter'
redef.value = 2000
setup.parameter_redefs.append(redef)
setup.calculation_type = olca.CalculationType.SIMPLE_CALCULATION
setup.impact_method = client.find(olca.ImpactMethod, 'ReCiPe Midpoint (H)')
setup.product_system = client.find(olca.ProductSystem, 'Test_Process')
setup.amount = 1.0
result = client.calculate(setup)
client.excel_export(result, 'result4.xlsx')
many many thanks in advance,
