python生成13位或16位时间戳以及反向解析时间戳的实例

我就废话不多说了，直接上代码吧！

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)

print ("test".center(20,"-"))
#! coding:utf-8
import uuid
print u"uuid1 生成基于计算机主机ID和当前时间的UUID"
print uuid.uuid1() # UUID('a8098c1a-f86e-11da-bd1a-00112444be1e')

print u"\nuuid3 基于命名空间和一个字符的MD5加密的UUID"
print uuid.uuid3(uuid.NAMESPACE_DNS, 'python.org') #UUID('6fa459ea-ee8a-3ca4-894e-db77e160355e')

print u"\nuuid4 随机生成一个UUID"
print uuid.uuid4()
#'16fd2706-8baf-433b-82eb-8c7fada847da'

print u"\nuuid5 基于命名空间和一个字符的SHA-1加密的UUID"
uuid.uuid5(uuid.NAMESPACE_DNS, 'python.org') #UUID('886313e1-3b8a-5372-9b90-0c9aee199e5d')

print u"\n根据十六进制字符生成UUID"
x = uuid.UUID('{00010203-0405-0607-0809-0a0b0c0d0e0f}')
print u"转换成十六进制的UUID表现字符"
print str(x)    # '00010203-0405-0607-0809-0a0b0c0d0e0f'''
