help with vba to python

[abell1234]

I am new to programming and I was wondering if anyone could help me with converting this vba script to python

Dim pMxDoc As IMxDocument
Dim pMap As IMap
Dim pCurve As ICurve
Dim pFromPoint As IPoint
Dim dXFrom As Double
Dim bSrefFromMap As Boolean
'=======================
'Adjust the parameter below
'bSrefFromMap = True ==> the coordinates will be calculated in the projection of the Map
'bSrefFromMap = False ==> the coordinates will be calculated in the projection of the data
bSrefFromMap = False
'=======================
If (Not IsNull([Shape])) Then
Set pCurve = [Shape]
If (Not pCurve.IsEmpty) Then
If (bSrefFromMap) Then
Set pMxDoc = ThisDocument
Set pMap = pMxDoc.FocusMap
pCurve.Project pMap.SpatialReference
End If
Set pFromPoint = pCurve.FromPoint
dXFrom = pFromPoint.X
End If
End If
