技巧25: 批量随机生成时间戳

实现方法

如下批量生成时间戳,random_timestamp函数中,hour传入小时(24小时制) ymd表示年月日,默认为2021-12-01

import random
import pandas as pd

def random_timestamp(hour, ymd='2021-12-01'):
    """
    生成年月日固定,分秒随机的时间戳
    :param ymd:
    :param hour: 传入小时
    :return:
    """

    def tstr():
        tms = set([random.randrange(1, 59, 2) for _ in range(20)])
        return [f'2020-12-01 {hour}:{ms}:{ms}' for ms in tms]

    return [pd.Timestamp(ws) for ws in tstr()]

调用

series = random_timestamp(9)
结果:
[Timestamp('2020-12-01 09:01:01'), Timestamp('2020-12-01 09:35:35'), Timestamp('2020-12-01 09:05:05'), Timestamp('2020-12-01 09:07:07'), Timestamp('2020-12-01 09:09:09'), Timestamp('2020-12-01 09:11:11'), Timestamp('2020-12-01 09:13:13'), Timestamp('2020-12-01 09:19:19'), Timestamp('2020-12-01 09:53:53'), Timestamp('2020-12-01 09:55:55'), Timestamp('2020-12-01 09:23:23'), Timestamp('2020-12-01 09:21:21'), Timestamp('2020-12-01 09:29:29'), Timestamp('2020-12-01 09:31:31')]
