How to use variable field name in arcpy.SearchCursor?

Question

I have code that says

fld = fieldName 
rows = arcpy.SearchCursor(fc)
for row in rows:
    x = row.fld

How do I use a variable for my field name in python ArcGIS 10 on windows? Thanks.

	I just found that in some older code I wrote. Thanks..but say I did not want to use the getValue method..is it possible using row.fld? – Justin Nov 5 '11 at 23:07
	Nope. row.fld would look for a field named "fld". – blah238 Nov 5 '11 at 23:09
	Not to pester but I get that..so row is an object??..looking for a what and how could....ah nevermind..I guess that is why they put the getValue method in there..Thanks! – Justin Nov 5 '11 at 23:13
	Yes, it's a Row object. arcpy uses some voodoo to go between ArcObjects and Python objects, you can step through it in a Python debugger to see it in action. – blah238 Nov 5 '11 at 23:25
