random模块练习

2、写一个产生双色球号码的程序，输入几就产生多少条

1、每次产生的里面不能有重复的

2、产生的号码要 1 2 3 4 5 6 7

1-32

1-17

01 02 03 04 05 06 07

 

第一种使用list写法 

import random

number = input('number:').strip()
if number.isdigit() and int(number)>0:
    l = []  这行解决重复
    while True:
        red = random.sample(range(1,34),6)
        red.sort()
        blue = random.sample(range(1,18),1)
        result = red + blue
        result = [ str(ball).zfill(2) for ball in result]
        seq = ' '.join(result)
        if seq not in l:
            l.append(seq)
            print('生成的双色球号码是：红球：%s 蓝球是:%s'%(' '.join(result[:6]),result[-1]))
            with open('seq.txt', 'w', encoding='utf-8') as fw:
                fw.writelines([line+'
' for line in l])#writelines解决写换行问题
        if int(number) == len(l):   这行解决个数一致和循环的结束 否则一直是死循环 
            break
第二种使用集合写法  

import random

 

reds = [ str(ball).zfill(2) for ball in range(1,34)]

blues = [ str(ball).zfill(2) for ball in range(1,18)]

 

 

def seq():

number = input('number:').strip()

if number.isdigit() and int(number)>0:

l = set()

while int(number)!=len(l):

red = random.sample(reds,6)

red.sort()

blue = random.sample(blues,1)

result = red + blue

seq = ' '.join(result)+' '

l.add(seq)

print('生成的双色球号码是：红球：%s 蓝球是:%s'%(' '.join(result[:6]),result[-1]))

 

with open('seq.txt','w',encoding='utf-8') as fw:

fw.writelines(l)

 

 

seq()
