CSV Data Analysis with Regex and Random Number Generation

This function reads a CSV file, uses regular expressions to match a specific format at the beginning of each row, calculates the average of the second field of the matching rows, then generates a random number and the current time.

    with open(arg1, 'r') as csvfile:

        data = list(csvreader)
    
    # 使用正则表达式匹配特定格式的字符串
    pattern = re.compile(arg2)
    
    # 使用math模块计算平均值
    numbers = [float(row[1]) for row in data if pattern.search(row[0])]
    average = sum(numbers) / len(numbers)
    
    # 使用random模块生成随机数
    random_number = random.random()
    
    # 使用sys模块获取当前时间
    current_time = time.time()
    
    # 返回计算结果
    return average, random_number, current_time
