random 及 账号生成代码练习

1. 取随机数  random 

import random

user = random.randint(1,10) #整数
y = random.uniform(1,100)#随机的小数
# print(round(f,2))
x = [159,753,8,5,2,5,6,96,6,3,36]
z = 'duhdhud8huidj5959562596'
print(random.sample(z,2)) #随机选择n个元素
print("==========================")
print(random.choice(z)) #随机选择1个元素
print("==========================")
random.shuffle(x) #洗牌，没有返回值，它会改变传入list的值
print(x)

2. 账号密码生成器

账号和密码
账号，必须包含字母和数字，长度在6-12之间
密码，必须包含大小写字母、数字、特殊符号，长度在8-12之间
输入几，就产生几条，并且用户名不能重复

import string,random
number = input("请输入产生数据的条数：").strip()
if number.isdigit():
    number = int(number)
else:
    print("请输入整数！")

def check_username(username):
    return set(username) & set(string.ascii_letters) and set(username) & set(string.digits)

def check_password(password):
    return set(password) & set(string.ascii_uppercase) and set(password) &  
    set(string.ascii_lowercase) and set(password) & set(string.digits) and 
    set(password) & set(string.punctuation)

l = {}

count = 0
while count<number:#1、2
    username_length = random.randint(6,12)
    username_list = random.sample(string.ascii_letters
                                  +string.digits,username_length)
    if check_username(username_list):
        username = ''.join(username_list)
    else:
        continue

    password_length = random.randint(8,12)
    password_list = random.sample(string.ascii_letters
                                  +string.digits+string.punctuation,password_length)
    if check_password(password_list):
        password = ''.join(password_list)
    else:
        continue

    if username not in l:
        count+=1
        l[username] = password

print(l)
