我一次只需要從串列中選擇一定數量的（隨機）關鍵字，而不是像現在這樣使用所有鍵進行 API 呼叫。我該如何繼續？
# 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))

如果要從串列中隨機選擇多個專案，可以使用random.choices(). 在這個例子中，它將選擇 4 個隨機關鍵字：
import random
keywords = ["Televisori", "Notebook", "Tablet", "Apple", "Samsung", "Smartwatch", "Auricolari Bluetooth", "Fotocamera",
"Videocamera"]
random_keywords = random.choices(keywords, k=4)

IIUC，您可以使用random.sample任何range(1,len(population))您喜歡的值：
（random.sample 從總體中選擇 k 個唯一的隨機元素）
>>> import random
>>> keywords = ["Televisori", "Notebook", "Tablet", "Apple", "Samsung", "Smartwatch", "Auricolari Bluetooth", "Fotocamera","Videocamera"]
>>> random.sample(keywords,5)
['Fotocamera', 'Videocamera', 'Notebook', 'Televisori', 'Samsung']
>>> random.sample(keywords,2)
['Televisori', 'Smartwatch']

您可以n像這樣從串列中獲取隨機元素：
import random
keywords = ["Televisori", "Notebook", "Tablet", "Apple", "Samsung", "Smartwatch", "Auricolari Bluetooth", "Fotocamera",
"Videocamera"]
random.shuffle(keywords)
n = 10
new_list = keywords[:n]
print(new_list)
