列表的 Unicode 問題。 無法在python中解決它

Question

我正在通過以下方式使用 pandas 從網站中提取數據/數據框：

import pandas as pd

jockeys = 'https://race.kra.co.kr/globalEn/jockeysBusan.do'
jdf = pd.read_html(jockeys)[0]

jdf_list = jdf.values.tolist()
print(jdf_list)

我得到的結果如下（只添加前幾個結果）：

[[1,
  'Chae Sang Hyun',
  'FREE',
  '2014/06/05',
  '262 (16/19/22)',
  '1789 (130/153/162)'],
 [2,
  'Choi Eun Gyeong',
  'FREE',
  '2016/06/18',
  '317 (19/22/38)',
  '1522 (90/120/140)'],
 [3,
  'Choi Si Dae',
  'FREE',
  '2007/05/18',
  '409 (58/34/34)',
  '5649 (750/658/594)'],
 [4,
  'Francisco Da Silva',
  'FREE',
  '2016/09/02',
  '375 (61/45/42)',
  '2255 (309/300/261)'],
 [5,
  '(-4)\xa0Gwon O Chan',
  'FREE',
  '2021/07/15',
  '154 (4/12/10)',
  '200 (4/14/10)']]

我一直在名字前得到這個“(-4)\xa0”。 我嘗試了以下幾種技術但沒有成功：

jdf_list_new =  jdf_list.encode('ascii', 'ignore').decode('utf-8')

和

jdf_list_new = unicodedata.normalize("NFKC", jdf_list)

在這里需要幫助！

Answer 1

\xa0是Unicode 字符 'NO-BREAK SPACE' 。 在獲取列表之前，您需要對數據框中的列進行編碼和解碼（ (-4)是網站中表格的一部分）

jdf = pd.read_html(jockeys)[0]
jdf['(allowance)Name'] = jdf['(allowance)Name'].str.encode('ascii', 'ignore').str.decode('utf-8')

輸出
