python - 如何迭代 HTML 数据中所有表的代码？

Question

这是我正在抓取的网页的 HTML 数据，正如您所看到的，它有多个选项卡。 (https://paste.pythondiscord.com/resaxivedo.py)

This is my code:
with open("tabledata.html", "r") as f:
    contents = f.read()
    outfile = open("table_data.csv", "w", newline='')
    writer = csv.writer(outfile)
    tree = BeautifulSoup(contents, "lxml")

    dates = tree.findAll(class_="date")
    list_of_dates = [date.text for date in dates]

    table_tag = tree.select("table")[0]
    tab_data = [[item.text for item in row_data.select("th,td")]
                for row_data in table_tag.select("tr")]
    writer.writerow(list_of_dates[0])
    for data in tab_data:
        print(' '.join(data))
        writer.writerow(data)

如您所见，我正在使用 [0] 选择表格和日期。 如何创建一个循环以便打印 HTML 页面中所有表格的数据？

类似这样的事情:

for table_tag in tree.select("table") :
    tab_data = [[item.text for item in row_data.select("th,td")]
                for row_data in table_tag.select("tr")]
    writer.writerow(list_of_dates[0])
    for data in tab_data:
        print(' '.join(data))
        writer.writerow(data)
