提示：这里可以添加本文要记录的大概内容：



提示：以下是本篇文章正文内容，下面案例可供参考


一、所学内容

1.1 QCalendarWidget

1.1.1 selectionChanged

1.2 QPalette(设置字体颜色)

pe = QPalette()
pe.setColor(QPalette.WindowText, Qt.red)
self.label_3.setPalette(pe)

二、完整代码

总结

提示：这里对文章进行总结：

例如：以上就是今天要讲的内容，本文仅仅简单介绍了pandas的使用，而pandas提供了大量能使我们快速便捷地处理数据的函数和方法。
