Python爱心表白代码

感觉的紫色要更加浪漫，其中的文字也是可以直接更改的，非常方便
<文末附带精品籽料>

• 改变爱心的颜色:

在源代码的13-15行位置，可以通过更改16进制颜色色值进行改变爱心的颜色，这里小编改了一点绿色！

可以看到爱心外圈变成了绿色，这里只能填写十六进制的颜色，rgb和英文颜色名字都是不支持的！

不知道怎么填颜色的小伙伴可以试试这款在线的调色工具，直接选择喜欢的色就可以复制16进制色值了，非常的方便！

图中框住的就是16进制的色值

• 改变文字

源代码181行的位置__爱你的XXX是右下角显示的文字，可以直接修改，在修改的时候注意引号不要删掉了，不然会报错，后面的微软雅黑和18分别是上面文字的字体和字号，也可以进行自定义设置，值得注意的是所设置的字体要保证设备上安装了，不然没有效果，字号是设置的越大字体就越大，184行的我爱你是爱心中间显示的文字，也可以支持直接更改的，后面的和上面的一样，按需修改即可！
