需要Wikipedia Web Scraper不断要求用户输入

Question

在执行和显示结果之后，我需要以下代码才能再次要求用户输入。我猜一段时间循环是最好的，但不确定如何做BeautifulSoup和请求使用的库。

任何帮助将不胜感激。

from bs4 import BeautifulSoup

user_input = input("Enter article:")

response = requests.get("https://en.wikipedia.org/wiki/" + user_input)
soup = BeautifulSoup(response.text, "html.parser")

list = []
count = 0

IGNORE = ["Wikipedia:", "Category:", "Template:", "Template talk:", "User:",
               "User talk:", "Module:", "Help:", "File:", "Portal:", "#", "About this", ".ogg", "disambiguation", "Edit section"]

for tag in soup.select('div.mw-parser-output a:not(.infobox  a)'):
    if count <= 10:
        title = tag.get("title", "")
        if not any(x in title for x in IGNORE) and title != "":
            count = count + 1
            print(title)
            list.append(title)
    else:
        break

使用返回语句

example

import requests
from bs4 import BeautifulSoup

IGNORE = ["Wikipedia:", "Category:", "Template:", "Template talk:", "User:",
          "User talk:", "Module:", "Help:", "File:", "Portal:", "#", "About this", ".ogg", "disambiguation",
          "Edit section"]


def get_user_input():
    user_input = input("Enter article:")
    if len(str(user_input)) > 0:
        return get_response(user_input)
    else:
        return get_user_input()


def get_response(user_input):
    response = requests.get("https://en.wikipedia.org/wiki/" + user_input)
    soup = BeautifulSoup(response.text, "html.parser")

    title_list = []
    count = 0

    for tag in soup.select('div.mw-parser-output a:not(.infobox  a)'):
        if count <= 10:
            title = tag.get("title", "")
            if not any(x in title for x in IGNORE) and title != "":
                count = count + 1
                print(title)
                title_list.append(title)
                print(title_list)
        else:
            return get_user_input()


if __name__ == '__main__':
    get_user_input()
