city = [it.split(',')[0] for it in all_info] #城市列表
city_inter = [it.split(',')[1:] for it in all_info]#地级市、区、县列表
while(1):
for num in range(len(city)):
print(num+1,city[num])
choice_city = int(input("选择你的城市的序号："))#输入立马把str转换成int

print(num+1,city_inter[choice_city-1][num])
xian = input("键入数字选择你所在的地方，键入非数字返回上一级：")
if xian.isdigit():
xian = int(xian)
