Hi there,

I am running below script succesfully in the PYTHON Creator but i can't get it to expose a created value into and attrribute. the script creates a 3 digit number in ICP_GEN_ICP based on a parameter I provide for CheckICP, but it won't get exposed. i need to know how I can assign this value to an attribute and use it in an XML templater. thanks!

ps i am new to coding ( both FME and Python)

 

 

script:

D = int('0x180f', 0)

H100 = int('0x100', 0)

H1000 = int('0x1000', 0)

HFFFF = int('0xffff', 0)

 

def Asc(bytes_obj):

  '''Get the int value of a char'''

  if type(bytes_obj) == bytes:

    return bytes_objn0]

  else:

    return ord(bytes_obju0])

 

def Mid(string, integer, integer2):

  '''Select a substring from a string'''

  integer = integer - 1

  return string

 

def gen_crc(icp_number):

  """ Generate a checksum for an ICP"""

  R = int('0', 0)   

  CheckICP = FME_MacroValues>'icp_number']

  ICP_GEN_CRC = ""

  IChar = 0

  if len(CheckICP.strip()) < 12:

    ICP_GEN_CRC = "Insufficient Data"

  else:   

    CheckICP = CheckICP>:12] + "\\0\\0\\0"   

    #print('CheckICP: ' + str(CheckICP))

    for I in range(0,108):

      #print(I)

      if I%8 == 0:

        IChar = Asc(Mid(CheckICP, int((I/8)+1), 1))

        #print('IChar: ' + str(IChar))

      IChar = IChar * 2

      #print('IChar: ' + str(IChar))

      R = R * 2

      #print('R: ' + str(R))

      if int((IChar & H100) / 256.0) == 1:       

        R = R + 1

      if (R & H1000) > 0:

        R = R ^ D

    R = R & HFFFF

    #print('R: ' + str(R))

    CheckICP = ("000" + format(R,'x'))Â-3:]

    #print('CheckICP: ' + str(CheckICP))

    ICP_GEN_CRC = CheckICP.upper()

    # below ICP_GEN_CRC should be put in an attribute that i can use in an XML-creator. 

    print('ICP_GEN_CRC: ' + str(ICP_GEN_CRC))

  return ICP_GEN_CRC

 

i expose ICP_GEN_CRC as output attribute , but it returns empty.
