I have 3 fields:

  1. "ISL_Numero" - Long (values are '1', '2', '3', '4' etc.)
  2. "Subtipo_IS" - Text (values are 'A', 'B', 'C' etc.)
  3. "Ambiente_C" - Text (values I want to calculate)

An example of what I want:

If "ISL_Numero" is 1 and "Subtipo_IS" is A, I want "Ambiente_C" to be Mangue

If "ISL_Numero" is 1 and "Subtipo_IS" is B, I want "Ambiente_C" to be Praia

If "ISL_Numero" is 2 and "Subtipo_IS" is A, I want "Ambiente_C" to be Cascalho

And so on ...

I tried the following:

Reclass(!ISL_Numero!,!Subtipo_IS!)
def Reclass(ISLNumero,SubtipoIS):
    if ( ISL_Numero == 1 and Subtipo_IS == "A" ) :
        return "Mangue"
    elif ( ISL_Numero == 1 and Subtipo_IS == "B" ) :
        return "Praia"
    elif ( ISL_Numero == 2 and Subtipo_IS == "A" ) :
        return "Cascalho"
    else:
        return ""

The calculation runs with no errors but the "Ambiente_C" doesn't get calculated as expected, it remains blank.

    the variable name in the if does not match the parameter name (ISLNumero vs ISL_Numero , and SubtipoIS vs Subtipo_IS) – JGH Jan 20 at 16:44

I'm not familiar with Python in ArcGIS specifically, but, as @JGH noted in their comment, the variables in your function definition (ISLNumero and SubtipoIS) must correspond to the names you use in the function body (ISL_Numero and Subtipo_IS). If there's some kind of error log in ArcGIS, I would expect to see a NameError: name 'ISL_Numero' is not defined from Python.

If the issue persists, as always, please provide additional details and we'll do our best to help.
