python作业/练习/实战：生成双色球小程序

作业要求：

每注投注号码由6个红色球号码和1个蓝色球号码组成。红色球号码从1--33中选择；蓝色球号码从1--16中选择

代码范例

import random
all_red_ball = [str(i).zfill(2) for i in range(1, 34)]
all_blue_ball = [str(i).zfill(2) for i in range(1, 17)]
def gen_seq():
    blue = random.choice(all_blue_ball)
    red = random.sample(all_red_ball,6)
    red = ' '.join(red)
    return '红球:%s 篮球:%s'%(red,blue)

all_seq=set()
num = int(input('请输入要产生多少条双色球:').strip())
while len(all_seq) != num:
    res = gen_seq()+'\n'
    all_seq.add(res)
with open('passwords.txt','w',encoding='utf-8') as fw:
    fw.writelines(all_seq)
