IBP banding data system: Internal maintenance specification

An object of this class represents the sex code. It is very similar to Section 36, “class AgeCodeField: Age code”, except for the list of valid codes; see the specification.

class SexCodeField(SingleField):
    '''Represents a sex code.

      Exports: as inherited.
    '''

Next we define the class attributes required by the SingleField interface. These define the set of valid sex codes, and a translation table that maps the older sex codes onto the newer set. Note that VALID_CODES does not contain a space character, because the sex code is required.

    VALID_CODES = "UMFX"
    OLD_TRANSLATOR = string.maketrans (
        "045",
        "UMF")

        SingleField.scanField(encounter, scan, fieldName,
                               SexCodeField, "sex code")
