pandas读取某列，转成成list，元素日期后面跟了一个.0，怎么才能去掉.0，并转成2022-08-01

Question

如上图，读取表格日期转成列表的时候，是这样的：
[20220822.0, 20220819.0, 20220818.0, 20220817.0, 20220816.0, 20220815.0, 20220812.0, 20220811.0, 20220810.0, 20220809.0, 20220808.0, 20220805.0, 20220804.0, 20220803.0, 20220802.0, 20220801.0, 20220729.0, 20220728.0, 20220727.0, 20220726.0, 20220725.0, 20220722.0, 20220721.0, 20220720.0, 20220719.0, 20220718.0, 20220715.0, 20220714.0, 20220713.0, 20220712.0, 20220711.0, 20220708.0, 20220707.0, 20220706.0, 20220705.0, 20220704.0, 20220701.0],
怎么转成2022-07-04.后面的.0去掉？
