one hot encoding classification

Question

I am having a CSV file like this

F1  |  F2  |  F3  |  F4  |  Label  

I used the get_dummies to change the label to a one-hot encoding representation, the data contains 3 different labels, so the file now looks like

F1  |  F2  |  F3  |  F4  |  Label1  |  Label2  |  Label3

let's say I want to use this data to train a machine learning model. I have to determine the features and label columns can I set it to:

Features, x = [0:3]
Labels, y = [4:6]

Is it right? I am thinking, by doing this way, maybe this could be understood as a multi-label problem since this is not! originally it was a multi-class classification.

Any help will be so much appreciated.
