How can I read CSV files interactively in Python?

import sc3
import datetime
import ctypes
import os
import csv
import win32gui, win32con

def get_open_file_name(title):
    filter='csv\0*.csv\0'
    customfilter='Other file types\0*.*\0'
    fname, customfilter, flags=win32gui.GetOpenFileNameW(
    InitialDir=project_file_path, 
    Flags=win32con.OFN_ALLOWMULTISELECT|win32con.OFN_EXPLORER,
    File='', DefExt='csv',
    Title=title,#
    Filter=filter,
    CustomFilter=customfilter,
    FilterIndex=0)
    return str(fname)

def get_shift_info():
    filename=get_open_file_name("Open CSV File")
    print(filename)
    list=[]
    with open(filename, encoding='utf8', newline='') as f:
        csvreader = csv.reader(f)
        for row in csvreader:
            list.append(row)
            print(row)
