python语法错误未声明变量，但没找到哪出问题

总是报错SyntaxError: Non-UTF-8 code starting with '\xa3' in file C:\Users\70686\source\repos\PythonApplication3\PythonApplication3\PythonApplication3.py on line 3, but no encoding declared; see https://python.org/dev/peps/pep-0263/ for details
下面是写的代码

price = 0
amount = 0
weight = int(input("plese enter weight："))
where=input("please enter place：")

where1="dongsansheng"or"qinghai"or"ningxia"or"hainan"
fprice1=12
eprice1=10

where2="xinjiang"or"xizang"
price2=20

where3="hongkong"or"aomen"or"taiwan"or"oversea"

if weight<=3:
    if where==where1:
        amount=fprice1*weight
    if where==where2:
        amount=price2*weight
    if where==where3:
        print("shipments from this area will not be accept")
if weight>3:
    if where==where1:
        amount=fprice1*3+eprice1*weight-eprice1*3
    if where==where2:
        amount=price2*weight
    if where==where3:
        print("shipments from this area will not be accept")
print("sent to the place:",where,"courierweight:",weight,"amount：",amount)

代码文件保存为 urf-8

遇到同样的问题，在第一行加了# -- coding: UTF-8 --，没啥用，题主解决了吗?
