Python爬蟲一共需要爬取65頁數據，每頁數據的列數不確定。現在我能把每一列的資料抓下來，但是因為列數不確定，寫入的檔案名稱就不能確定。問題在於怎麼才能把第x列資料寫入第x個檔案。也就是如何才能動態選擇file=的檔名。程式碼如下：

f_1 = open('fitment/1.txt', 'a') f_2 = open('fitment/2.txt', 'a') f_3 = open('fitment/3.txt', 'a') for i in range(66): pr = random.choice(proxy) url = 'https://*****' + str(i) + '****' page_url = requests.get(url, headers=head, proxies=pr) page_get = page_url.text page_text = BeautifulSoup(page_get, 'lxml') fitment_1 = page_text.find_all('tr', {'class': 'fitment listRowEven'}) for each_tag_1 in fitment_1: td_text_1 = each_tag_1.find_all('td') for x in range(len(td_text_1)+1): print(td_text_1[x].string, file=)

網頁的結構類別如下，每個tr標籤即為一列，具體要抓取的資料位於每個td標籤內
