Pulling & Reading Date from UDF that Compare it to Live Data

[firebird]

Hello Everyone!
Would you help me solve the following problem i have:
I am trying to write a user defined function that would load, read date from a csv file, itereate through the column where row of values being examined are located, check those values against current value (price = live.get_live_price("AAPL"))and then take an action (in this case to print it out) if the comparison meet certain condition (row value < price or row == price). when i run the script i do not get any error message and yet there is no output at all.
Thank you

#import all necessary modules
import csv
from yahoo_fin import stock_info as live
import pandas as pd
from datetime import date
import datetime


def readfile(filepath):
    #get Apple's latest quote price
    price = live.get_live_price("AAPL")

    with open(r'C:\Users\...\Desktop\AAPLCSV', 'r') as file:
        reader = csv.reader(file)
        for index, row in reader:
            if row[3] < price:
                return price
            elif row[3] == price:
                return row[3]
            print(price, row[3])
