How to count the number of node and tag in each node in OpenStreetMap XML?

Question

Python

Coordinates given. How many node tags do not contain any tag tag (the first number in the answer), and how many contain at least one tag tag (the second number in the answer):
map2.osm = href=" https://www.openstreetmap.org /api/0.6/map?bbox=103... ">
My code:
from urllib.request import urlopen, urlretrieve
from bs4 import BeautifulSoup
xml = open('map2.osm', 'r', encoding='utf8') .read()
soup = BeautifulSoup(xml, 'lxml')
d = []
for node in soup.find_all('node'):
for i in node('tag'):
a = (node, i)
d.append (a)
print(d)
How to proceed, how to display exactly the number of tags for each node in the directory?
Thank you!
