一道简单的python编程？
def demo(m, n):
for ji in range(1, m + 1):
tu = m - ji
if ji * 2 + tu * 4 == n:
return (ji, tu)
else:
return (-1, -1)
m, n = input('输入鸡兔数，脚数：').split(',')
if demo(int(m), int(n)) == (-1, -1):
print('输入数据出错！')
else:
print('%d只鸡，%d只兔。' % demo(int(m), int(n)))
python简单的编程代码
输入两个数字，比较大小，然后按照大小输出
def cmpNum():
a = input("请输入一个数字：")
b = input("请输入一个数字：")
if a = b:
print(a, b)
else:
print(b, a)
cmpNum()
结果一：
请输入一个数字：159
请输入一个数字：456
456 159
结果二：
请输入一个数字：9568
请输入一个数字：1452
9568 1452

这是一个简易版贪吃蛇的代码，虽然结构简单，但是该有的功能都是完整的，可玩性也不错
