无法使用BeautifulSoup和python检索父标签

<div class="parent">
    <div class="child">Child 1</div>
    <div class="child">Child 2</div>
</div>

from bs4 import BeautifulSoup

html = '''
<div class="parent">
    <div class="child">Child 1</div>
    <div class="child">Child 2</div>
</div>
'''

soup = BeautifulSoup(html, 'html.parser')
child = soup.find(class_="child")
parent = child.parent

print(parent)

<div class="parent">
    <div class="child">Child 1</div>
    <div class="child">Child 2</div>
</div>
