matching_items = []
for item in yourlist:
result = re.search('[sS]ome expression', item) # and of course
s/search/match, if you're interested in matching
if result:
matching_items.append(item)
Or you could go for more terse syntax via list comp:
matching_items = [item for item in yourlist if re.search('contains', item)]
Or if you want one at a time you could change [] for () and turn it into a
generator expression.
However, the list itself doesn't have any method for matching. Here are its
"public" methods:
append
count
extend
index
insert
pop
remove
reverse
sort
