To print a test field (TestField) from a test feature class (TestFC) in a test file geodatabase (Test.gdb) located in a temporary folder (C:\Temp):
with arcpy.da.SearchCursor(r"C:\Temp\Test.gdb\TestFC",["TestField"]) as cursor:
for row in cursor:
print row[0]
In Emacs, basic search tool (I-Search) allows you to search after or before the location of your cursor.

my_array = array('i', [1,2,3,4,5])
my_array.append(6)
