Need help understanding simple Array code. Please.

[stluwa]

import pandas
import numpy
dataframe = pandas.read_csv("C:\Users\stluwa\cars.csv")
array = dataframe.values
X = array[:,0:8]
Y = array[:,8]

My problem is, I can not seem to figure out what is happening in the lines:

X = array[:,0:8]
Y = array[:,8]

My biggest question is what the [:,0:8] means. I'm doing some feature selection stuff, but i never learned python.

Hey, I'm not sure why it's [:,0:8] or [:,8] but it should instead be [:0:8] and [:8] respectively.

These are slices. You can read more about them here.
