Question

因此，我一直在尝试找出一些问题并继续学习。我创建了一个脚本，在其中打印出数字，但是其中一些数字具有禁用的类，而我想做的就是我只想打印出那些在“类”中没有禁用的数字

try:
    select_tags = bs4.find_all('select', {'autocomplete': 'off'})
except Exception:
    select_tags = []

data_products = []
for select_tag in select_tags:

   test = select_tag.find_all('option')
   for hehe in test[1:]:

       print(hehe)
       print("----------")

       if hehe.select('select > option(.disabled)'):
           print('Skip')
           continue

       try:
           found = hehe.text
           found = found.replace(" ", "")
           found = found.replace("\n", "")
       except Exception:
           found = None

       found_data = {
           "found": found
       }
       data_products.append(found_data)


print(data_products)

输出：

----------
<option class="" value="11_141">
                            (Number 1)                        </option>
----------
<option class="" value="11_142">
                            (Number 2)                        </option>
----------
<option class="" value="11_143">
                            (Number 3)                       </option>
----------
<option class="disabled ReminderRevealButton" value="11_144">
                            (Number 4)                       </option>
----------
<option class="" value="11_145">
                            (Number 5)                        </option>
----------
<option class="disabled ReminderRevealButton" value="11_137">
                            (Number 6)                        </option>
----------
<option class="" value="11_136">
                            (Number 7)                        </option>
----------

我想要输出的是：

(Number 1)
(Number 2)
(Number 3)
#Skip number 4 because it has Disabled
(Number 5)
#Skip number 6 because it has disabled
(Number 7)

我需要做什么才能解决该问题？

下面的代码跳过已禁用类的选项。

try:
    select_tags = bs4.find_all('select', {'autocomplete': 'off'})
except Exception:
    select_tags = []

data_products = []
for select_tag in select_tags:

   test = select_tag.find_all('option')
   for hehe in test[1:]:

       if "disabled" not in hehe:
           print(hehe.text)
