Python unicode浮动错误

Question

我有一个从 HTML 页面中提取数据的 python 脚本。在 HTML 中有一个带有浮动的表格。当我执行findAll 和赋值语句时，它会将其分配给 unicode 类型的变量。但我需要变量为浮点类型。我以为我可以做一个float() 转换，但这会引发错误：

  File "percentages.py", line 52, in <module>
    top_score = float(row.findAll('td')[2].text.strip())
ValueError: invalid literal for float(): 62.4%

sn-p 代码如下：

for link in stat_links:
    r = requests.get(link)
    soup = BeautifulSoup(r.text, "html.parser")
    table = soup.find('table', class_="tr-table datatable scrollable")
    team_rows = table.findAll('tr')
    team_rows = team_rows[1:]
    for row in team_rows:
        if row.findAll('td')[0].text.strip() == '1':
            top_score = float(row.findAll('td')[2].text.strip())
        if row.findAll('td')[0].text.strip() == '351':
            lowest_score = float(row.findAll('td')[2].text.strip())

for row in team_rows:
    if row.findAll('td')[1].text.strip() == sys.argv[1]:
        temp = float(row.findAll('td')[2].text.strip())
        if link == "https://www.teamrankings.com/ncaa-basketball/stat/average-scoring-margin":
            top_score = top_score + abs(lowest_score)
            temp = temp + abs(lowest_score)
            lowest_score = 0
        temp = (temp - lowest_score) / (top_score - lowest_score)
        team_one = team_one + temp

Answer 1

您可以将% 符号替换为空字符串：

top_score = float(row.findAll('td')[2].text.strip().replace("%", ""))
