Using open.readlines, why won't it return the list?

Question

My understanding of this part of sentiments is that I need to open the positive words file and make it all into a list, I thought I could do this with open.readlines, but it isn't working. Can someone let me know what's wrong with my code? Thanks

def __init__(self, positives, negatives):
    """Initialize Analyzer."""
    poslist = open("positive-words.txt").readlines()
    print(poslist)
    # TODO

we are inside a class in python, one way is to declare a set (not ordered), the way to do it would be the following:

def __init__(self, positives, negatives):
        """Initialize Analyzer."""
        # TODO
        self.positives = set()
        file = open("positive-words.txt", "r")
        for line in file:
            ......
                self.positives.add(line)
        file.close()
