Python3 简单的三级列表思路(初学者 比较low)

info = { '北京':{ '沙河':['benz','momo'], '朝阳':['北土城','健德门'], '国贸':['女明星','HP'] }, '山东':{}, '广东':{} } while True: for i in info: print(i) user_choice = input('please input your choice>>>').strip() if user_choice in info: while True: for i2 in info[user_choice]: print(i2) user_choice2 = input('please input your choice>>>').strip() if user_choice2 in info[user_choice]: while True: for i3 in info[user_choice][user_choice2]: print(i3) user_choice3 = input('please input your choice>>>').strip() if user_choice3 == 'q': exit()
