Hi, everyone.  
In ITK python version, there is a enum ChoiceMethod\_KEEP in class itkMergeLabelMapFilterEnums in the file itkMergeLabelMapFilterPython.py.  
In my code

```auto
mergeLabelMapFilter = itk.MergeLabelMapFilter.New(labelMap1, 
                                                      labelMap2, 
                                                      labelMap3,
                                                      Method=???)

```

I don’t know how to set ??? in Method.

Take a look at the [migration guide](https://github.com/InsightSoftwareConsortium/ITK/blob/master/Documentation/ITK5MigrationGuide.md#strongly-typed-enumerations). Try `Method=itk.itkMergeLabelMapFilterEnums.ChoiceMethod_KEEP`.
