First declare your list properly, separated by commas. You can get the unique values by converting the list to a set.
mylist = ['nowplaying', 'PBS', 'PBS', 'nowplaying', 'job', 'debate', 'thenandnow'] myset = set(mylist) print(myset)
If you use it further as a list, you should convert it back to a list by doing:
mynewlist = list(myset)
Another possibility, probably faster would be to use a set from the beginning, instead of a list. Then your code should be:
output = set() for x in trends: output.add(x) print(output)
As it has been pointed out, sets do not maintain the original order. If you need that, you should look for an ordered set implementation (see this question for more).
