本文介绍了Python如何生成13位或16位时间戳，并详细讲解了如何反向解析这些时间戳，同时拓展讨论了Python生成唯一Id的多种方法。

import datetime
import time


def get_float_time_stamp():
    datetime_now = datetime.datetime.now()
    return datetime_now.timestamp()


def get_time_stamp16():
    # 生成16时间戳  eg:1540281250399895  -ln
    datetime_now = datetime.datetime.now()
    print(datetime_now)

    # 10位，时间点相当于从UNIX TIME的纪元时间开始的当年时间编号
    date_stamp = str(int(time.mktime(datetime_now.timetuple())))

    # 6位，微秒
    data_microsecond = str("%06d" % datetime_now.microsecond)

    date_stamp = date_stamp + data_microsecond
    return int(date_stamp)


def get_time_stamp13():
    # 生成13时间戳  eg:1540281250399895
    datetime_now = datetime.datetime.now()

    # 10位，时间点相当于从UNIX TIME的纪元时间开始的当年时间编号
    date_stamp = str(int(time.mktime(datetime_now.timetuple())))

    # 3位，微秒
    data_microsecond = str("%06d" % datetime_now.microsecond)[0:3]

    date_stamp = date_stamp + data_microsecond
    return int(date_stamp)


def stampToTime(stamp):
    datatime = time.strftime("%Y-%m-%d %H:%M:%S", time.localtime(float(str(stamp)[0:10])))
    datatime = datatime + '.' + str(stamp)[10:]
    return datatime


if __name__ == '__main__':
    a1 = get_time_stamp16()
    print(a1)
    print(stampToTime(a1))
    a2 = get_time_stamp13()
    print(a2)
    print(stampToTime(a2))

补充拓展：关于python生成唯一Id的几种方法小结

# coding:utf-8
import random


def createRandomString(len):
    print('wet'.center(10, '*'))
    raw = ""
    range1 = range(58, 65)  # between 0~9 and A~Z
    range2 = range(91, 97)  # between A~Z and a~z

    i = 0
    while i < len:
        seed = random.randint(48, 122)
        if ((seed in range1) or (seed in range2)):
            continue;
        raw += chr(seed);
        i += 1
    # print(raw)
    return raw


print
createRandomString(20)
