TypeError：不可用的类型：＆＃x27; slice＆＃x27;使用美丽的小组

Question

我希望此代码在for循环的第一个元素之外打印出所有内容。但是我有一个切片错误。

from bs4 import BeautifulSoup
import requests
from openpyxl import Workbook

f = open(r'C:\Users\anilo\Documents\Anilo\Projekte\Python\Verben\Konjugation des Verbs machen _ alle Zeitformen _ Duden.html', 'r', encoding='utf-8')
html_doc = f.read()

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

uls = soup.find_all('ul', class_='accordion__list content-column')[1]
for li in uls:
    konjugation = li.text
    konjugation_neu = konjugation.replace('1', '')
    print(konjugation_neu)

输出：

Präteritum
machte (mich/mir)
machtest (dich/dir)
machte (sich)
machten (uns)
machtet (euch)
machten (sich)

li in uls中的LI [1：]：导致错误typeerror：不可用的类型：'sl​​ice'

任何人都知道如何在不编辑的情况下执行技巧我的大部分代码，因为我需要这个面试项目。

提前致谢。

Answer 1

问题是您从resultset中选择一个元素：

soup.find_all('ul', class_='accordion__list content-column')[1]

因此，您无法将其切成薄片 - 删除元素选择并添加您的切片：

uls = soup.find_all('ul', class_='accordion__list content-column')
for li in uls[1:]:
    konjugation = li.text
    konjugation_neu = konjugation.replace('1', '')
    print(konjugation_neu)

注： 您的切片将迭代所有UL，除非第一个 - 如果应该选择第一个切片看起来像[：1]

示例，

以真正获取每个＆lt ; li＆gt;在您的＆lt; ul＆gt;切片时，您必须添加额外的迭代：

from bs4 import BeautifulSoup
html_doc='''
<div class="accordion-tables__group"><div class="accordion-table"><ul class="accordion__list sidebar-column dashed"><li class="accordion__item">Hidden title</li><li class="accordion__item">ich</li><li class="accordion__item">du</li><li class="accordion__item">er/sie/es</li><li class="accordion__item">wir</li><li class="accordion__item">ihr</li><li class="accordion__item">sie</li></ul><ul class="accordion__list content-column"><li class="accordion__item">Präsens</li><li class="accordion__item">mache (mich/mir)<sup>1</sup></li><li class="accordion__item">machst (dich/dir)<sup>1</sup></li><li class="accordion__item">macht (sich)<sup>1</sup></li><li class="accordion__item">machen (uns)<sup>1</sup></li><li class="accordion__item">macht (euch)<sup>1</sup></li><li class="accordion__item">machen (sich)<sup>1</sup></li></ul></div><div class="accordion-table"><ul class="accordion__list sidebar-column dashed"><li class="accordion__item">Hidden title</li><li class="accordion__item">ich</li><li class="accordion__item">du</li><li class="accordion__item">er/sie/es</li><li class="accordion__item">wir</li><li class="accordion__item">ihr</li><li class="accordion__item">sie</li></ul><ul class="accordion__list content-column"><li class="accordion__item">Präteritum</li><li class="accordion__item">machte (mich/mir)<sup>1</sup></li><li class="accordion__item">machtest (dich/dir)<sup>1</sup></li><li class="accordion__item">machte (sich)<sup>1</sup></li><li class="accordion__item">machten (uns)<sup>1</sup></li><li class="accordion__item">machtet (euch)<sup>1</sup></li><li class="accordion__item">machten (sich)<sup>1</sup></li></ul></div></div>
'''

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

uls = soup.find_all('ul', class_='accordion__list content-column')
for ul in uls[1:]:
    for li in ul.find_all('li'):
        print(li.text.replace('1', ''))

输出

Präteritum
