Instead of using csv module in Python, I would suggest using the Pandas library. Refer the following code
import pandas as pd
df1 = pd.read_csv(csv file) # read csv file and store it in a dataframe
Suppose if you want to extract columns A,B and C from your csv file then use the code in the following line
my_columns = df1[["A","B","C" ]]
print(my_columns) #this will print columns A,B,C
