厄。。。不知道诶！

fly-陌路 发表于 2020-12-18 20:44

不发个运行的图片吗

迦南圣经 发表于 2020-12-18 20:50

大佬包装个exe看看

renpeng009 发表于 2020-12-18 20:51

好像只能windows下执行

Cool_Breeze 发表于 2020-12-18 21:09

Windows 环境直接保存.py 文件运行就行了啦！图片就没有必要放了吧！有些浪费资源！

tinglie 发表于 2020-12-18 21:21

用pyinstall给白嫖党打包成EXE吧。。。他们实在是太懒了

已收藏，学习代码提升自己

运行后没弹窗，控制台乱码咋回事
