如何在csv文件中搜索存储在另一个csv文件中的关键字？

Question

I'm trying to search a csv file having 150K+ row using keywords stored in a csv file with several dozen row. What's the best way to go about this? I've tried a few things but nothing has gotten me very far.

Current Code:

import csv
import pandas as pd
data = pd.read_csv('mycsv.csv')
for line in data:
    if 'Apple' in line:
        print(line)

This isn't what I want, it's just what I currently have. The for loop is my attempt at just getting output using one of the keywords from the smaller csv file. So far I'm either getting errors or there is no output.

Edit: I forgot to mention that the large csv file I'm trying to search from is from a web link, so I don't think with open is going to work

Supposing that your keywords are stored in a file named keys.csv and in each row of that file, there's only one keyword, like this:

Orange
Apple
...

then try this:

with open('mycsv.csv') as mycsv, open('keys.csv') as keys:
    keys = keys.readlines()
    for line in mycsv:
        if any([key[:-2] in line for key in keys]):
            print(line)
