先上代碼 1：

s = """ 安師大安師大安師大安師大安師大安師大安師大安師大安師大安師大安師大安師大安師大安師大安師大安師大安師大安師大安師大安師大安師大安師大安師大安師大安師大安師大安師大安師大安師大安師大安師大安師大安師大安師大安師大安師大安師大安師大安師大安師大安師大安師大安師大安師大安師大安師大安師大安師大安師大安師大安師大安師大安師大安師大安師大安師大安師大安師大安師大安師大安師大安師大安師大安師大安師大安師大安師大安師大安師大安師大安師大安師大安師大安師大安師大安師大安師大安師大安師大安師大安師大安師大安師大安師大安師大安師大安師大安師大安師大安師大安師大安師大安師大安師大安師大安師大安師大安師大安師大安師大安師大安師大安師大安師大安師大安師大安師大安師大安師大安師大安師大安師大安師大 """

print(s)

執行代碼 1，會報錯：SyntaxError: Non-UTF-8 code starting with '\xe5' in file

再上代碼 2：

s = """ 師大安師大安師大安師大安師大安師大安師大安師大安師大安師大安師大安師大安師大安師大安師大安師大安師大安師大安師大安師大安師大安師大安師大安師大安師大安師大安師大安師大安師大安師大安師大安師大安師大安師大安師大安師大安師大安師大安師大安師大安師大安師大安師大安師大安師大安師大安師大安師大安師大安師大安師大安師大安師大安師大安師大安師大安師大安師大安師大安師大安師大安師大安師大安師大安師大安師大安師大安師大安師大安師大安師大安師大安師大安師大安師大安師大安師大安師大安師大安師大安師大安師大安師大安師大安師大安師大安師大安師大安師大安師大安師大安師大安師大安師大安師大安師大安師大安師大安師大安師大安師大安師大安師大安師大安師大安師大安師大安師大安師大安師大安師大安師大安師大 """

print(s)

代碼 2 就是把代碼 1 的 s 字符串變量里，隨便刪一個字，比如刪開頭的安，然后就可以成功打印結果了。

靠！！！這是什么鬼？？？就差一個字符就能有這么大的變化？

當然解決代碼 1 還有種辦法，就是文件頭部加# -*- coding: utf-8 -*-，但是為什么呢？？ python3 不就是默認 utf-8 的嗎？

執行環境：

1、macos

2、vscode / sublime text 3 都不可以

3、python3.7 ( anaconda 的和自己編譯裝的 python 3.7 親測都不行) [但是網頁版的這個 “python 3 在線執行” 卻可以 https://c.runoob.com/compile/9 ]
