Import CSV file and make each column its own list

Question

I have a csv file that contains data like this with a lot of rows:

2017, UNC (1), Gonzaga (1), Oregon (3), South Carolina (7)
2016, Villanova, (2), UNC (1), Oklahoma (2), Syracuse (10)

I am trying to import the file and make each column into its own list in the easiest way possible in python.

Answer 1

This will give you a list of columns, each column being a list of items.

import pandas as pd

def get_columns(csv_file):
    df = pd.read_csv(your.csv)

    columns = []
    for column in df:
        columns += column
    return columns

Answer 2

You can use the built in csv module standard with every python installation.

import csv
header1 = []
header2 = []
# so on
with open('file.csv') as csvfile:
    reader = csv.DictReader(csvfile, fieldnames=['header1', 'header2', 'header3', 'header4', 'header5'])
    for row in reader:
        header1.append(row['header1'])
        header2.append(row['header2'])
        # so on
