百钱买百鸡，现有100文钱，公鸡5文钱一只，母鸡3文钱一只，
小鸡一文钱3只，要求：公鸡，母鸡，小鸡都要有，把100文钱
买100只鸡，买的鸡是整数。多少只公鸡，多少只母鸡多少只小鸡？

import  random
a = True
while a:
    a = 91
    list1 = ['公鸡', '母鸡', '小鸡']
    gongji = 1
    muji = 1
    xiaoji = 3
    while 0<=a<=91 :
        if random.choice(list1)=='公鸡':
            gongji = gongji + 1
            a = a - 5
        elif random.choice(list1)=='母鸡':
            muji = muji + 1
            a = a - 3
        elif random.choice(list1)=='小鸡':
            xiaoji = xiaoji + 3
            a = a - 1
        if a==0:
            print("公鸡有%d只，母鸡有%d只，小鸡有%d只,余额=%d" % (gongji, muji, xiaoji, a))
            a = False
            break
        else:
            continue

 

第二种方法是：只得出一种花费100块钱来购买100只的鸡的方法

for i in range(1,20):
    for j in range(1,33):
        for k in range(3,98,3):
            if i+j+k==100 and 5*i + 3*j + k//3 ==100:
                print("公鸡：",i,"母鸡：",j,"小鸡：",k)
