Does feature order impact Decision tree algorithm

Question

I read some material:

• decision tree document in sklearn

• A Quora Answer

However I can find if I change feature order(the set of feature name: [a,b,c] change into [b,a,c]) in the data. Does this actually affect decision tree result?

Answer 1

Not really. Sklearn generally uses Cart trees where the best split is decided by picking the feature that minimizes a cost function. So the order of column doesn't really matter.
