Python去除HTML标签时报expected string or bytes-like object如何解决

问题根因 #

你拿到的raw_html是bs4.element.ResultSet类型，本质是BeautifulSoup查询返回的标签对象列表，不是字符串，所以正则替换、直接传入BeautifulSoup解析都会触发「expected string or bytes-like object」类型错误。

解决方法 #

不需要额外转字符串、用正则二次解析，直接遍历ResultSet里的每个标签对象提取文本即可：

# 方法1：直接提取所有div的文本，逐行拼接
output = []
for div_tag in raw_html:
    # get_text()可直接提取标签内的纯文本
    output.append(div_tag.get_text())
final_text = '\n'.join(output)
print(final_text)

运行后就会输出你要的格式：

A financial model should be developed when the business planning process has reached the _______ planning stage
The correct answer is: Operational
Selling new products to existing customers is a strategy of
The correct answer is: Product development
In the strategic review and strategic planning process Product/Portfolio Analysis follows immediately after the
The correct answer is: Industry and competitor analysis

如果需要只输出单组题目+答案，按需切片取列表元素即可：

# 只取第一组题目和答案
first_q = raw_html[0].get_text()
first_a = raw_html[1].get_text()
print(f"{first_q}\n{first_a}")
