The following will remove duplicates.

results = ["Anna","Michael","Anna","Juliet","Juliet", "Anna"]
results = list(dict.fromkeys(results))
print(results)

Output:

['Anna', 'Michael', 'Juliet']

You can conver the list to a set, which has no duplicates by definition.

results = set(["Anna","Michael","Anna","Juliet","Juliet", "Anna"])

If you need the type of the result to be a list, you can simply convert it back:

results = list(set(["Anna","Michael","Anna","Juliet","Juliet", "Anna"]))
