why cut the last element?

[SysuJayce]

def read_embedding_list(file_path):
    embedding_word_dict = {}
    embedding_list = []
    with open(file_path) as f:
        for row in tqdm.tqdm(f.read().split("\n")[1:-1]):
            data = row.split(" ")
            word = data[0]
            embedding = np.array([float(num) for num in data[1:-1]])
            embedding_list.append(embedding)
            embedding_word_dict[word] = len(embedding_word_dict)

    embedding_list = np.array(embedding_list)
    return embedding_list, embedding_word_dict

Can anyone tell me why the last element was cut?
like this one: data[1:-1]
