写函数时出错

  • 772

先生们，请帮助，我写了这个东西：

import re
from wiki_req import get_topic_page

def get_topic_text (topic):
    html_content = get_topic_page(topic)
    words = re.findall("[а-яА-Я\-]+", html_content)
    text = " ".join(words)
    return text

print(get_topic_text ("Москва"))

他给了我这个

Traceback (most recent call last):
  File "C:/Users/admin/PycharmProjects/helloworld/ООП/ООП4/index.py", line 10, in <module>
    print(get_topic_text ("Москва"))
  File "C:/Users/admin/PycharmProjects/helloworld/ООП/ООП4/index.py", line 6, in get_topic_text
    words = re.findall("[а-яА-Я\-]+", html_content)
  File "C:\Users\admin\AppData\Local\Programs\Python\Python37-32\lib\re.py", line 223, in findall
    return _compile(pattern, flags).findall(string)
TypeError: expected string or bytes-like object

请帮帮我

这是原始的 wiki_req 文件本身

from requests import get
"""https://ru.wikipedia.org/wiki/Россия"""

def get_link(topic):
    link = "https://ru.wikipedia.org/wiki/" + topic
    return link

def get_topic_page (topic):
    link = get_link(topic)
    html_content = get(link).text
    with open("new.html", "w", encoding="utf-8") as f:
        f.write(html_content)
    return True

print(get_topic_page ("биржа"))
python

    get_topic_page模块中的函数wiki_req返回类型为 的值bool，在您的情况下为True。

    您正在尝试将该值True用作正则表达式搜索的字符串（或文件），这就是发生错误的原因。

    您的替代价值声明没有意义，请参阅：

    words = re.findall("[а-яА-Я\-]+", True)  # Возникнет ошибка!

    最有可能的是，错误只是在模块wiki_req中，您应该在其中返回HTML-code，而不是布尔值：

    def get_topic_page (topic):
    link = get_link(topic)
    html_content = get(link).text
    with open("new.html", "w", encoding="utf-8") as f:
        f.write(html_content)
    return html_content

    另一种解决方案是从函数get_topic_page写入结果的文件中读取：

    def get_topic_text (topic):
    get_topic_page(topic)
    with open('new.html', encoding='utf-8') as f:
        html_content = f.read()

    words = re.findall("[а-яА-Я\-]+", html_content)
    text = " ".join(words)
    return text
