1、生成随机数
（1）生成随机整数：
import random num = random.randint(1, 50) # 闭区间 print(num)
（2）生成随机偶数：
import random num = random.randrange(0, 101, 2) # 左闭右开区间，取0-100的整数 print(num)
（3）生成随机浮点数：
import random num = random.random() # 生成0-1之间的随机浮点数 num2 = random.uniform(1, 10) # 生成的随机浮点数归一化到区间1-10 print(num) print(num2)
2、生成随机字符
import random alphabet = 'abcdefghijklmnopqrstuvwxyz!@#$%^&*()' char = random.choice(alphabet) print(char)
3、生成随机字符串
（1）生成指定数量的随机字符串
方法1：
import random alphabet = 'abcdefghijklmnopqrstuvwxyz!@#$%^&*()' characters = random.sample(alphabet, 5) print(characters) #['d', 'q', '@', 'u', 'e']
方法2：
#数字+字母+符号 def getRandChar(n): l = [] #sample = '0123456789abcdefghijklmnopqrstuvwxyz!@#$%^&*()-+=.' sample = random.sample(string.ascii_letters + string.digits, 62)## 从a-zA-Z0-9生成指定数量的随机字符： list类型 sample = sample + list('!@#$%^&*()-+=.')#原基础上加入一些符号元素 for i in range(n): char = random.choice(sample)#从sample中选择一个字符 l.append(char) return ''.join(l)#返回字符串
（2）从a-zA-Z0-9生成随机字符串
import random import string value = ''.join(random.sample(string.ascii_letters + string.digits, 8)) print(value) #CLJ7vWBd
（3）随机选取一个元素
import random table = ['剪刀', '石头', '布'] print(random.choice(table)) #石头
（4）随机选取两个元素
import random table = ['剪刀', '石头', '布'] print(random.sample(table,2)) #['剪刀', '布']
3、将序列顺序打乱
import random a=[1,3,5,6,7] random.shuffle(a) print(a) #[6, 7, 5, 3, 1]
import random import string num = 1 while num < 100: username = ''.join(random.sample(['0','1','2','3','4','5','6','7','8','9','z','y','x','w','v','u','t','s','r','q','p','o','n','m','l','k','j','i','h','g','f','e','d','c','b','a'],5)) password = random.randint(10000,99999) txt= str(username) + "," + str(password) + "\n" num +=1 with open("user.txt","a") as f: f.write(txt) print(num)
生成数据量比较大的随机字符串：
import random seclength = 4000 def contextRandom(): global ItemVale global ItemLen alphabet = '1234567890!@#$%^&*abcdefghijklmnopqrstuvwxyz@1234567890' * 100 random_len = random.randint(1, seclength) print('随机值：{},type:{}'.format(random_len,type(random_len))) ItemLen = random_len + 31 print('>>>secStore 随机长度是：{}'.format(ItemLen)) ItemVale = ''.join(random.sample(alphabet, random_len)) + '123456@jodie_sec_write_read_del' print('>>>secStore 随机内容是：{}'.format(ItemVale)) return ItemLen,ItemVale contextRandom() """ 随机值：2813,type:<class 'int'> >>>secStore 随机长度是：2844 >>>secStore 随机内容是：9020ec^b&81td0yhlt@&6422@xu0qx8v@725m@vt6l7q1z488o^uvqkjfvop137*^w1q4@8@1p2b!69gub6s@th0l@553j9i^422$iz@x3g7vz1gh9td7r@&#g8^p84s@54x4*lpflya%8#6!p*gk085sl5u&@uwbj6697xwc6222^hxts5guz70#!rd0w@hn6ys!!4ri1798z4n1@!@dx5b8qjxbtxkn74%44p*cx4r5^@1s65b@ax2q7lx1zavt0&*z40&m$2a!59511076w15c5f27os7k5nj2uenvx2l8^0$^0gddjfm#3gbj9ogj1d1woy*msumh#vgd9y2rtcyk&3u5jf8vz%o05&c9l$9vynh$!df398@4b@566980bre6%paevy97e36rpj97^i@peoq*4s1o9c84*5@22z6@m391jb1vu2cy7314#ti%b%z@%7ealb%@3%2sa@!!4vfwjbw9&82k98ldvfn77h6xnbo96k5*1r5@g68&#sp046s&q3dhx&11zt1et3mf008aaa02x1$5v$h0397qmj83%fec7jq0jd82180sst2b^m$@nd6pcal#$6412%uh9%c**6aozqy0ov1ao0@c07ra7b^fu%264ubk2tv100og1ovv8b%qwr^rx9637sm^27^6^x*@pi*35oeqlmxhq@m%2@43663ifr426h1yz7rf39@cya9$8c$t%9b0791ke92pq7527b891&!685rk77qternq8!2akdl%@hjhm521d$1ik3h@vxa7di20553kb&1huv6##n6o736py#ky41jdp3&be02@mp09td2c2@a805ku6gtb9wz#8pm26$4#9ai5p#v0#9xfg5m4!2k2x41k2r52@gbuv31yoexdnsqn30ew4e65hg%5q49^*60y70l4rvk9i1p6984583o1h48a$89y1h#w4g41*z&nfmz156bsm!az4g342@3i0a17fgk$ft@2$358@4g9v751g^e1%tdz468q*8w&edhn@4rmf29jdq1s%56@p0i$5!oa&!*6$@81f53$qbg@f@27z22ynrduth6nld295cv0alu81ac9axi%3^%^6aqkt3w0b3j^sx9623vctg4o*9m4!qa@^dt@!ny355%n932@!7t4zpi@%y293&65n@9yv3ujv!5$4lfqx9o$nm4jd&dz042i914k9r5x6!p6ge@t105zf83o#&63c&bs!c@l@^94bn@fx!w3@9wyv%^*pafor4#8fdv%^3x4!0!598x@8n87$i83fblyj9jg59rgo9#75j7233lqabk8e@2#%1mnxtqc9lr1g@mki^#un7590%kd38xll772qenm@*l1h26*57rba4yh&y8k0&eti1vdjc!0!7f0shsz!k3b%3@47*70$zncc5ae%soqe$um94#25u%s97md4rjag8@09az69#@30^aj4zn8i*8u4!v124l$29#jfa@%&f@q4!b3qlp*ly0xu124@35610o5d4ool02@86i3nde0p23ldji4z7^78n9m4d#g$fqf76zk3mrdfi%u1@olv8qk6736#8xmyf@@qhf&66ub#u!ec89vt&njbx57c$y11fhz0nc9!n9p05i5w^wwa7fzf6y!b4q!c*^7o@99j^o344320zjz^fv57a05zesse2239p3pl@4t46zz586ajb3mm6i67un$*0q8#38oy$yw46c0v^51p#928*a$@r1uvt533dhj2&pgan!85^lq0sl38lf*609$4039884r06t##vd03ul1o7ppf^g4tif87o@35&p93e$6&p7qwytekv72gdrm*z^$p@1m757y!24#4m9j5d0g2eps6g0#o2fpf*&%ze1jxf#4s3!tvn41%^!@67qs*0a1z93@@9srarioxe$$36wjuwx601fpwju97!onb3&yz1lnm2@@&t345&7o^84dk2j#72oc@@79hkw02!z#7l0b4q4x3to85g8%9s2z46cjrix31y@c1nk6i%8mz0c0z4613t*l*@06p^*%3x*td6&l6kn3@$i6wh%m0i1f894zi17e!c3z241027owv3mvbp&@iol%2kvn1c91g2@x#*73n%yb^@k85el375ne5*ku4#9to1^di7&r$j!kf5mt9@u02%*nducc3efhj8y$6!th$n#wiufyljwz#8d%m9jn@x7mmrm*192p##29r@p@7rh0p258z@5e9@@wan2h#57z8206g2^yq9nyomyl@j!5x6skk9f2b5az5cu5#^k&9710$2y83i^6w131w@skz7e9$lbj9j6m5w9dstf&^765043a9xdelogj7!^q6juf@$@r98!ic!it52bygl1nl#5%wr245msqijr^99^%!4nfkq57yc*5zyl7o$@60&i624sl73g860p2*zvxzf@02owj$5las3^8374e6@&z1$u5wq%#5q03@u!5jc*h135^a!b0a&9i@1^fp07*2p%t*l$*zok!rb6cf06z0!taq622d#qxr$5t82i7okl8y0i9j0cjave091v9%1rrhhu08yd0o90ump8pq6ca0l0422bzt45z73z51^96hp191uk07189027&0jlgk24!i5bc5339@3j1v^*es7g0n5ov!$5j%^zg!agn!6^8s6ul*4u9t%f94u6k17r$046^4z8ot36ce59qcs8u^7x&j790002qg0gz70%hnniq1g1*9$bs6jux9bif1$743^qjmb!v!4lnhet@dew7g@*eagfdcpu71u7kdh14@1l4jqflcm&w8hl05r6m30h5*36wq9%8amqd123456@jodie_sec_write_read_del """
