我如何创建一个函数来分离和平均这些数据的行

def separateAndAverageRows(data):
    separated_rows = []
    averaged_rows = []

    # 分离行
    for row in data:
        separated_rows.append(row)

    # 计算每行平均值
    for row in separated_rows:
        average = sum(row) / len(row)
        averaged_rows.append(average)

    return averaged_rows
