Get unique values from a list in python

I want to get the unique values from the following list:

['nowplaying', 'PBS', 'PBS', 'nowplaying', 'job', 'debate', 'thenandnow']

The output which I require is:

['nowplaying', 'PBS', 'job', 'debate', 'thenandnow']

This code works:

output = []
for x in trends:
    if x not in output:
        output.append(x)
print(output)

is there a better solution I should use?
