[Tutor] Searching for items in two lists.

Yes, I was just lazily splitting a string into a list, cause I wanted to
avoid typing quotes! :-)

>> lookin=f2.readlines()

Yep, each line in the file represents an entry, so I don't need to split
them.

>> for item in lookfor:
>> 	for searched_string in lookin:

Yes indeed!

Right!

The format of the two files is like so:

lookfor:
123456
a12345
b12345
c12345

lookin:
"'Briggs', 'Joebob'", 'my house', '12345', 'Yadda yadda'
"'Briggs', 'Joejim'", 'Guy house', '12222', 'Fu-Bar'
"'Briggs', 'Joeweasel'", 'Thai house', 'b3214', 'Foo Bar'
"'Briggs', 'Joeblow'", 'thy house', 'c5588', 'Yadda yammar'

For each line in lookfor I want to search each line in lookin and return the
entire line to a list and thereby to a file. For some reason, I seem to be
finding more than my share of items.... several times! :-)
