习题6：二.3 随机密码生成

编写程序在26个字母大小写和9个数字组成的列表中随机生成10个8位密码。

import random
num_ls = []  # 创建数字、小写字母、大写字母空列表
str_ls = []
STR_ls = []
for i in range(ord('1'),ord('9') + 1): # 将数字对应的unicode码添加到对应list中
    num_ls.append(i)
for i in range(ord('a'),ord('z') + 1): # 将小写字母对应的unicode码添加到对应list中
    str_ls.append(i)
for i in range(ord('A'),ord('Z') + 1): # 将大写字母对应的unicode码添加到对应list中
    STR_ls.append(i)
ls = num_ls + str_ls + STR_ls
def passWord(ls):
    """随机从列表中选取8个unicode码，并转化成字符"""
    s = []
    while len(s) < 8:
        s.append(random.choice(ls))
    for i in s:
        print(chr(i),end = '')
def passWord_group(ls):
    g = []
    while len(g) < 10:
        g.append(passWord(ls))
        print('')
    return g

    
passWord_group(ls)

原答案有误，正确的答案为：

from random import *
seed(0x1010)
s = 'abcdefghijklmnopqistuvwxyzABCDEFGHIJKLMNOPQISTUVWXYZ0123456789!@#$%^&*'
ls = []
ex = ' '
while len(ls) < 10:
    pwd = ' '    
    for i in range(10):
        pwd += s[randint(0,len(s)-1)]
        if pwd[0] in ex:   #原书中的答案，此行没缩进
            continue
    else:
        ls.append(pwd)
        ex += pwd[0]
        
with open("python二级冲刺试卷\\模拟试卷C\\随机密码.txt",'w',encoding = 'utf-8') as f:
    f.write('\n'.join(ls))
