<div class="col-lg-10">
<select class="form-control m-select2 func_select2_manual" name="product_size_id">

Answer 1

尝试使用xmltodict解析html

import xmltodict

html_string = '''
your_html_string
'''

parsed_html_dict = xmltodict.parse(html_string)
result = []

for option in parsed_html_dict['div']['select']['option']: # selection is wrt your example
    result.append({
        'data-stock': option['@data-stock'],
        'text': option['#text']
        })
print(result)

Answer 2

我已使用BeautifulSoup解析html

from bs4 import BeautifulSoup
html_doc = """<div class="col-lg-10">
<div class="col-lg-10">
<select class="form-control m-select2 func_select2_manual" name="product_size_id">
<option data-height="40" data-length="245" data-stock="12" data-weight="500" data-width="110" value="656">36</option>
<option data-height="40" data-length="250" data-stock="9" data-weight="500" data-width="110" value="657">37</option>
<option data-height="40" data-length="255" data-stock="8" data-weight="500" data-width="110" value="658">38</option>
<option data-height="40" data-length="260" data-stock="9" data-weight="500" data-width="110" value="659">39</option>
</select>
</div>
"""


soup = BeautifulSoup(html_doc, 'html.parser')

options = soup.find_all('option')

option_data_stock_list = []
option_text_list = []

for option in options:
    option_data_stock = option.attrs.get('data-stock')
    option_text = option.text.strip().strip('\n')
    option_data_stock_list.append(option_data_stock)
    option_text_list.append(option_text)
    print(option_data_stock, option_text)

print(', '.join(option_data_stock_list))
print(', '.join(option_text_list))
