網絡使用python和BS4

Question

刮我想從下面這個網址bloomberg代碼廢數據。

我想獲取下列標籤及其相應的值的文本：

*

1. open. 
2. previous close. 
3. ytd return. 
4. market_cap. 
5. day range. 
6. 52wk_range. 
7. current_per_ratio. 
8. shares_outstanding. 
9. volume. 
10. one_year_return. 
11. Earnings_per_share. 
12. price_sales. 
13. divident_indecated_gross_yeild. 

*

我嘗試過，但失敗了，不知道在Python中用bs4做正確的方法。

請指引我實現它，我想要的方式。

for cell in soup.find_all("div", class_='data-table data-table_detailed'): 
    name = "" 
    namecell = cell.find("div", class_="cell__label", text=True) 
    if namecell is not None: 
     name = namecell.get_text(strip=True) 
    price_chage = cell.find("div", class_="cell__value cell__value").get_text(strip=True) 
    data+=("%s: Price Change: %s," % (name, price_chage))

所有誰被傳遞，並給予負面票怪才，這是代碼，我寫的。恭喜我！如果你不能幫助任何人，那麼不要投反對票。

for cell in soup.find_all("div", class_='cell '): 

    namecell = cell.find("div", class_="cell__label", text=True).get_text(strip=True) 
    if cell.find("div", class_=("cell__value cell__value_down"),text=True): 
     classText="cell__value cell__value_down" 
    elif cell.find("div", class_=("cell__value cell__value_up"),text=True): 
     classText = "cell__value cell__value_up" 
    else: 
     classText = "cell__value cell__value_" 

    value=cell.find("div", class_=(classText),text=True).get_text(strip=True) 
    if namecell and value is not None: 
     tbl_data.append(namecell+":"+value) 
print tbl_data 

輸出是：
