改了之前的代码，加入while：
#coding: utf-8
print("王小狗丑不丑？丑→1；不丑→2")
answer = input(">")
if answer == "":
print("恭喜你，你的选择很正确！") elif answer == "":
print("要不，你再考虑一下？ ")
print("王小狗究竟丑不丑？丑→1；不丑→2")
real_answer = input(">")
while real_answer != "" and real_answer != "" :
print("别捣乱！王小狗丑不丑？丑→1；不丑→2")
real_answer = input(">")
while real_answer == "" or real_answer != "":
print("我觉得差不多了，你就说王小狗到底丑不丑？丑→1；不丑→2")
real_answer = input(">")
if real_answer == "":
print("说这种话，你自己信吗！")
elif real_answer == "":
pass
else:
print("请你认真回答。")
print("恭喜你，可以去睡觉了！") else:
print("不好好做题，你想作甚王小丑！")
print("请重新回答，王小狗丑不丑？丑→1；不丑→2")
last_answer = input(">")
while last_answer != "" and last_answer != "":
print("快回答！王小狗丑不丑？丑→1；不丑→2")
last_answer = input(">")
while last_answer == "" or last_answer != "":
print("无论如何，王小狗丑不丑？丑→1；不丑→2")
last_answer = input(">")
if last_answer == "":
print("不能因为你的善良而埋没了良知！")
elif last_answer == "":
pass
else:
print("你踏马好好回答行不行？")
print("恭喜你，可以去睡觉了！") input()
精简：
#coding: utf-8
print("王小狗丑不丑？丑→1；不丑→2")
answer = input(">")
while answer !='':
if answer=='':
print("回答错误，请重新输入")
else:
print("别瞎搞，好好回答")
answer = input(">")
print("恭喜你，答对了！")
input()
注：因为是做给人玩的小游戏，导出exe文件，结尾input（），使运行框不关闭
