从字典中显示列表时无法删除 []

  • 772

我编写了一个机器人来解析 CS:GO 游戏的市场，并为它编写了一个电报机器人。我拿价格、名字和贴纸，如果没有贴纸，我就不写了，但我把列表里的贴纸写下来。显示某个项目的信息时，有贴纸时，会显示贴纸列表，但带有括号和引号，请帮我删除它们。

电报中的消息，您需要删除括号

['Наклейка: ALEX (золотая) | Берлин 2019', 'Наклейка: ALEX (золотая) | Берлин 2019', 'Наклейка: ALEX (золотая) | Берлин 2019', 'Наклейка: ALEX (золотая) | Берлин 2019']

如何从 json 文件中获取信息

    with open('resultpmarketcsgo.json', 'r', encoding='utf8') as file:
        itemlist = json.load(file)
    for item in itemlist:
        if item.get('sticker_url') is not None:
            text_ss = f'{hlink(item.get("title_item"), item.get("url_item"))} \n {item.get("price_item")} \n {item.get("sticker_url")}'
            await message.answer(text_ss)
        else:
            text_bs = f'{hlink(item.get("title_item"), item.get("url_item"))} \n {hbold(item.get("price_item"))}'
            await message.answer(text_bs)

带有信息的 json 文件

  {
        "title_item": "ПП-19 «Бизон» | Space Cat (Поношенное)",
        "price_item": "37.95 RUB",
        "url_item": "https://market.csgo.com/item/4726068058-188530139-PP-Bizon%20%7C%20Space%20Cat%20%28Well-Worn%29/"
    },
    {
        "title_item": "SG 553 | Заросшие руины (После полевых испытаний)",
        "price_item": "15.6 RUB",
        "url_item": "https://market.csgo.com/item/4841323188-519977179-SG%20553%20%7C%20Lush%20Ruins%20%28Field-Tested%29/",

       "url_item": "https://market.csgo.com/item/4726068058-188530139-PP-Bizon%20%7C%20Space%20Cat%20%28Well-Worn%29/"

                       ]
       }

for item in itemlist:
      print('-'*50)
      sticker = ''
      if stic := item.get('sticker_url'):
            sticker = '\n' + '\n'.join(stic)
      text_ss = f'{item.get("title_item")}\n{item.get("url_item")}\n{item.get("price_item")}{sticker}'
      print(text_ss)
