Question

我正在尝试创建一个跟踪程序并使用BeautifulSoup，并要求图书馆从Steam网站上节省一些价格。然后使用openpyxl将这些价格值写入excel文件。

在前四个游戏中，一切工作都非常顺利。当我尝试将更多游戏标题添加到列表中时，该错误存在。

请参见下面的代码

将空心骑士项目添加到列表中后，我开始出现此错误：

TypeError：“ str”和“ int”的实例之间不支持“ <”

即使我没有使用任何比较符号来比较此程序中的值。

旁注：我有一个json文件，存储了将值放入Excel的下一行。在程序执行完上面的所有代码后，程序会将行值更新1。请参见下面的功能updateTrackingLines（）

cookies = {'birthtime': '568022401'} # For Steam's age verification

wishlist = [

    sheets = wb.get_sheet_names()

    today = today.strftime("%m/%d/%Y")
    lines = getTrackingLines()
    for i in range(0,l):
        sheet = wb.get_sheet_by_name(sheets[i])
        html = requests.get(wishlist[i],cookies=cookies)
        page_soup = soup(html.content, "html.parser")
        price = page_soup.find("div",{"class":"game_purchase_price price"}).text.strip()
        price = price[1:len(price)]
        sheet.cell(lines[i],2, value = float(price)) # updating cells
        sheet.cell(lines[i],1, value = today)
        print("successed updating " + sheet.title)
    wb.save("C:\Python37\SteamTracker\ProductsTracker.xlsx")
    updateTrackingLines() # See explaination of this func above

Answer 1

问题解决了！

好像我在这里使用的json文件在我身上造成了一个令人生畏的小错误。

当我在json中添加其他项时，我不小心将值行编码为str类型，而不是普通的int。

我们需要一个int值来定位excel工作表中的单元格，但是我的代码值行是str类型。

我最好学会注意打字错误。

如错误所述，<用于比较str和int。

  File "C:\Users\Han\AppData\Local\Programs\Python\Python37\lib\site-packages\openpyxl\worksheet\worksheet.py", line 236, in cell
    if row < 1 or column < 1:
TypeError: '<' not supported between instances of 'str' and 'int'

从代码行

    if row < 1 or column < 1:

似乎您以str或row的身分通过了column。在查看您的代码时，lines[i]可能就是str。

  File "c:/Python37/SteamTracker/main.py", line 58, in updateProducts
    sheet.cell(lines[i],2, value = float(price)) # updating cells

我不知道为什么会收到“ TypeError：'str'和'int'实例之间不支持的TypeError：'<'”错误
