Using Python : first example

Python is very useful to express some developments which are not easy to express in NDF.

For example, python can easily do mathematical calculs. To calculate (TAccesseurA + TAccesseurB)/(log TAccesseurC), you can write in NDF :

<ndf>
ResultOfComplexCalcul is TAccesseurRealDivide :
  AccesseurNumerateur = TAccesseurRealAdd :
                          RealList =
                          [
                            TAccesseurA,
                            TAccesseurB,
                          ]
  AccesseurDenominateur = TAccesseurRealLogN :
                            AccesseurReal = TAccesseurC
</ndf>                            

In python, this is much simpler and easy to modify :

<ndf>
ResultOfComplexCalcul is TAccesseurRealPython :
  ParamsNoEval = MAP
  [
    ('A', TAccesseurA),
    ('B', TAccesseurB),
    ('C', TAccesseurC),
  ]
  Code = """
    import math
    result = (A.Value + B.Value) / math.log(C.Value)
  """
</ndf>

You can use thoses NDF Accessors in the same way

• TAccesseurBooleanPython
• TAccesseurStringPython
• TAccesseurStringListPython
