#洗牌打乱
#random() 方法返回随机生成的一个实数，它在[0,1)范围内。
#shuffle() 方法将序列的所有元素随机排序。

#洗牌打乱
data=list(range(10))

 密码生产：10台服务器，生产10个密码随机密码

    passwd_data = 'passwd_data.txt'
    with open(passwd_data, 'a') as f:
        for i in range(1,16):
            info = '192.168.1.%s   root  22 ' %i
            info = info+passwd_code() + '\n'
            print(info)
            f.write(info)

 

 

优化后代码：

import string,random

def passwd_code():
    ret=[]
    num = string.digits
    alf = string.ascii_letters
    res = num + alf
    s = random.sample(res,10)
    ret = ''.join(random.sample(s, 10))
    return ret

if __name__ == '__main__':
    print('USER','PORT','PASSWORD')
    passwd_data = 'passwd_data.txt'
    strtmp = ''
    with open(passwd_data, 'a') as f:
        for i in range(1,16):
            info = '192.168.1.%s   root  22 ' %i
            strtmp = strtmp+info+passwd_code() + '\n'
        print(strtmp)
        f.write(strtmp)  #字符串最后一次写入
