关于Windows:python 3:如何将输出打印到控制台和文件

Python 3 : How to print output to both Console and File

所以基本上我还在学习python编程，目前我在Github上找到了一些代码。

基本上，代码在执行时工作正常，它将输出打印到终端/控制台。但是，我希望将输出保存到文件中，因此遵循了一些教程，并成功地将输出保存到文件中，但是输出没有显示在终端中。

我的问题是，如何执行这个python脚本来显示终端上的输出，同时将输出写入.txt文件？

下面是我正在处理的python代码：

看看最后几行语句来打印输出。

PS：这不是我的代码，我只是想通过Python学习一些ASCII艺术。PSS：我正在使用带有cygwin64终端的windows来执行代码。

问候。
