Just ignore NavigableString objects while iterating through the tree:
from bs4 import BeautifulSoup, NavigableString, Tag
response = requests.get(url)
soup = BeautifulSoup(response.text, 'html.parser')
for body_child in soup.body.children:
if isinstance(body_child, NavigableString):
continue
if isinstance(body_child, Tag):
print(body_child.name)
