how to direct python to fetch string in a different file

Question

how do i change the "keyword" in parameter ('pegasus') to redirect to a separate txt file. so later I just write whatever items I want to scrape in the file txt. Example of Pegasus, Phoenix, Lucid then the keyword parameter is directed to a different txt, inside the txt it contains a list of those objects and once it has finished scraping the pegasus it will scrape next item which is Phoenix, and so on

import requests
import csv

key = input('enter name file u want :')
write = csv.writer(open('output/{}.csv'.format(key), 'w', newline=''))
header = ['Name', 'Price', 'Seller', 'Order']
write.writerow(header)

url = 'https://api-gateway.itemku.com/v1/product'
count = 0
for page in range(1, 2):
parameter = {
    'is_include_game': 1,
    'is_include_item_type': 1,
    'is_include_item_info_group': 0,
    'is_include_order_record': 1,
    'is_from_web': 1,
    'is_include_upselling_product': 1,
    'game_id': 29,
    'per_page': 18,
    'page': page,
    'sort': 'cheap',
    'is_auto_delivery_first': 1,
    'is_with_promotion': 1,
    'keyword': 'pegasus'
}

r = requests.get(url, params=parameter).json()

products = r['data']['data']
for p in products:
    name = p['name']
    price = p['price']
    seller = p['seller']
    order = p['order_record']
    count += 1
    print('No :', count, 'name:', name, 'price:',
          price, 'seller:', seller, 'order:', order)
    write = csv.writer(
        open('output/{}.csv'.format(key), 'a', newline=''))
    data = [name, price, seller, order]
    write.writerow(data)
