Here search is actually a function because you left out the
parentheses after split(). But with them, search would be a list. The
argument to count() must be a string.

Do you want a count per line or for the whole file? For the whole file
you could do something like

search_terms = raw_input ("Enter your search item ").split()  # Note
the final ()
data = open(look_in).read()
count = 0
for term in search_terms:
  count += data.count(term)

The last three lines could also be written as
count = sum(data.count(term) for term in search_terms)
