Assuming

aa = ["foo", "bar", "baz"]

and

findit = "bar"

the print statement will only be executed when findit == item.

First iteration of your for loop:

item = "foo"
if "foo" == "bar": # False
   print "foo"     # not executed, nothing printed

Second iteration:

item = "bar"
if "bar" == "bar": # True
    print "bar"    # prints bar

Third iteration:

item = "baz"
if "baz" == "bar": # False
    print "baz"    # not executed, nothing printed

This depends on what you want to achieve. Can you tell us?
