if row[0] is equal row[1] then row[2] is None

I am writing my very first script in Python 2.7. (And this is my very first question/post here and about Python scripting at all)

Solved/found out almost all problems except one.

I can not figure out how to write the following for arcpy.da.UpdateCursor:

if row[0] is equal row[1] then row[2] is None

Any suggestion is appreciated.

I am expecting a relevant answer to my question.

EDIT: Here is the working code and a solution to my question.

import arcpy

    fc = 'C:/DB/yourDB.gdb/yourFeatureClass.shp'
    fields = ['field0', 'field1', 'field2']
    
    with arcpy.da.UpdateCursor(fc, fields) as cursor:
        for row in cursor:
            if (row[0] == row[1]):
                row[2] = None
            cursor.updateRow(row)
    
    del cursor

Here is the correct code and a solution for my question.

import arcpy

    fc = 'C:/DB/PGDB.gdb/Parcel_point.shp'
    fields = ['NEWNUMBER', 'NEWNUMBER1', 'NEWNUMBER2']
    
    with arcpy.da.UpdateCursor(fc, fields) as cursor:
        for row in cursor:
            if (row[0] == row[1]):
                row[2] = None
            cursor.updateRow(row)
    
    del cursor
