Python reads a column or several columns of a csv file

import csv
import pandas as pd

with open('D:\Data\New folder\list3.','r') as csvfile:
reader = (csvfile)
column1 = [row[1]for row in reader]
print(column1)


# The following is read according to the column properties
d = pd.read_csv('D:\Data\New folder\list3.', usecols=['case', 'roi', 'eq.diam.','x loc.','y loc.','slice no.'])
print(d)
