ArcMap Field Calculator Python

Question

Hello everyone

I have a question concerning Python in ArcMap (field calculator):

I want to write following code with python, in attributes table; field calculator. But I can't.

Could you help me,

Thanks.

Dim pSpRef1 As ISpatialReference 
Dim pSpRFc As SpatialReferenceEnvironment 
Set pSpRFc = New SpatialReferenceEnvironment 
Dim pGCS As IGeographicCoordinateSystem

Set pGCS = 
pSpRFc.CreateGeographicCoordinateSystem(esriSRGeoCS_NAD1983) 
Set pSpRef1 = pGCS 
pSpRef1.SetFalseOriginAndUnits -180, -90, 1000000

Dim pPCS As IProjectedCoordinateSystem 
Dim pSpRef2 As ISpatialReference 
Set pPCS = 
pSpRFc.CreateProjectedCoordinateSystem(esriSRProjCS_NAD1983USA_
Albers) 
pPCS.SetFalseOriginAndUnits 0, 0, 1000 
Set pSpRef2 = pPCS 
Dim dblArea As double 
Dim CenterX As double 
Dim CenterY As double 
Dim pArea As IArea

Set pArea = [shape]

Dim pGeo As IGeometry 
Set pGeo = pArea 
Set pGeo.SpatialReference = pSpRef1 
pGeo.Project pSpRef2

Set pArea = pGeo 
dblArea = pArea.Area

theKm = dblArea / 1000000

This is a situation related to Phd. I thought these steps wouldn't work, sometimes different results can come out, but they did.
thanks again, DanPatterson

Seeing there are existing tools to accomplish this task, and yet you want to write it on your own without explaining why, it seems like this may be a question for school/studies.  If you can provide a reason why you have to write it in Python yourself, people may be more willing to help or offer additional suggestions.

Thank you again,

I examined it, but not  figure it out. I'm new in Python.

I want to write  with Python Parser of the Field Calculator.
