Informações Adicionais
This is a quirk of the is the operator in Python (which checks whether two objects point to the same memory), and how strings are stored (equivalent alphanumeric strings like 'Texas' point to the same object in memory when invoked, strings such as 'South Dakota' do not point to the same object in memory. The top answer at https://stackoverflow.com/questions/16756699/is-operator-behaves-differently-when-comparing-strings-with-spaces describes this well). String equality has to be checked using == (which checks for value equality) for this reason.Solução Provisória
It is to be noted other operators can be used in the scenario to return the results when matching them up with the fields having values of either spaces or some other special characters.
Expression 1:
def Reclass(value1):
if value1 == 'South Dakota':
return 1
else:
return 0
Expression 2:
def Reclass(value1):
if 'South Dakota' in value1:
return 1
else:
return 0
