除了UUID之外,我们还可以使用其他方法来生成唯一的字符串。一种常见的方法是基于时间戳和随机数的组合来生成唯一的字符串。下面是一个示例: importtimeimportrandomdefgenerate_unique_string():timestamp=str(int(time.time()))random_num=str(random.randint(1000,
函数中利用string.ascii_letters生成所有的字母字符,然后利用random.choice随机选择字符,并通过列表解析生成指定长度的字符串。 方法二: 使用UUID生成字符 另一种常用的方法是使用Python的uuid模块生成唯一标识符,然后取其中的部分字符作为结果。下面是一个示例代码: importuuiddefgenerate_uuid_string(length):returnstr(uu...
