Is there a real C4.5 implementation in Python ? (handling missing value)
I don't think there is a C4.5 implementation in a popular python library. Your options are :


Try github implementations such as : https://github.com/geerk/C45algorithm
Try getting R implementations with rpy package : see over there for an exemple of how that would work (C5.0) https://stackoverflow.com/questions/41070087/calling-c5-0-in-python
