Select n keywords from list

I need to select only a certain number of (random) keywords from the list at a time and not make an API call with all the keys as is the case now. How can I proceed?

    # Search keywords definition
keywords = ["Televisori", "Notebook", "Tablet", "Apple", "Samsung", "Smartwatch", "Auricolari Bluetooth", "Fotocamera",
            "Videocamera"]

# run bot function
def run_bot(bot, keywords):
    # shuffling keywords list
    random.shuffle(keywords)

    # start loop
    while True:
        try:
            items_full = []

            # iterate over keywords
            for el in keywords:
                # iterate over pages
                for i in range(1, 10):

                    items = search_items(el, CATEGORY, item_page=i)

                    # api time limit for another http request is 1 second
                    time.sleep(1)

                    items_full.append(items)

            # concatenate all results
            items_full = list(chain(*items_full))
