python报错

FutureWarning: save is not part of the public API, usage can give unexpected results and will be removed in a future version
  writer.save()

升级了Python 到3.11.0，然后pandas中ExcelWriter也跟着升级了，以下是版本：

然后是执行原来的导数据到Excel的代码报错警告：
 FutureWarning: save is not part of the public API, usage can give in unexpected results and will be removed in a future version
 

writer = pd.ExcelWriter("excel_path.xlsx")
..... 
writer.save()
解决办法：
升级之后，writer.save（）接口已经私有化，调用close()即可。

writer = pd.ExcelWriter("excel_path.xlsx")
#..... 
writer.close()
