uuid str int 之間的轉換

import uudi #str 轉 uuiduuid.UUID(’12345678123456781234567812345678’)uuid.UUID(hex=’12345678123456781234567812345678’)uuid.UUID(’{12345678-1234-5678-1234-567812345678}’)uuid.UUID(’urn:uuid:12345678-1234-5678-1234-567812345678’)#Out：UUID(’12345678-1234-5678-1234-567812345678’) uuid.UUID(fields=(0x12345678, 0x1234, 0x5678, 0x12, 0x34, 0x567812345678))#Out：UUID(’12345678-1234-5678-1234-567812345678’) #int 轉 uuiduuid.UUID(int=0x12345678123456781234567812345678)#Out：UUID(’12345678-1234-5678-1234-567812345678’) #uuid 轉 strstr(uuid.uuid4())#Out：’a0565f88-b20a-4cc1-a6de-11f046bb7100’type(str(uuid.uuid4()))#Out：strpython的uuid模塊提供UUID類和函數uuid1(), uuid3(), uuid4(), uuid5() 來生成1, 3, 4, 5各個版本的UUIDuuid.uuid1([node[, clock_seq]]) : 主機ID, 序列號, 和時間戳來生成UUID, 可保證全球范圍的唯一性uuid.uuid3(namespace, name) : 基于命名空間和名字的MD5散列值uuid.uuid4() : 基于隨機數uuid.uuid5(namespace, name) : 基于命名空間和名字的SHA-1散列值，同uuid3

補充拓展：python字符串和time互轉與時間的加減另加uuid

咱們看代碼吧！

# -*-coding:utf-8 -*-__author__ = 'ZJL' import uuid,time,datetime #uuid4產生32位隨機字母加數字print(str(uuid.uuid4()).replace('-',''))#uuid3產生基于名字的MD5散列值print(str(uuid.uuid3(uuid.NAMESPACE_DNS,'username')).replace('-','')) #time轉字符串time_num = time.strftime(’%Y-%m-%d %H:%M:%S’,time.localtime(time.time()))print(time_num) #字符串轉timet = time.strptime(time_num, ’%Y-%m-%d %H:%M:%S’)y,m,d,H,M,S = t[:6]print(t)print(datetime.datetime(y,m,d,H,M,S)) #時間的加減now_time = datetime.datetime.now()#當前時間加半小時yes_time = now_time + datetime.timedelta(hours=+0.5)#比較時間大小if now_time>yes_time: print('ok')else: print('no')#當前時間減一天# yes_time = now_time + datetime.timedelta(days=-1)yes_time_nyr = yes_time.strftime(’%Y-%m-%d %H:%M:%S’)print(yes_time_nyr)

結果：

import time, datetime#一個月前today1 = datetime.datetime.today()astmonth = datetime.datetime(today1.year, (today1.month - 1), today1.day, today1.hour, today1.minute,today1.second)

以上這篇python str字符串轉uuid實例就是小編分享給大家的全部內容了，希望能給大家一個參考，也希望大家多多支持好吧啦網。
