Ok,
First of all, I reformatted your code a bit so that I could follow better, and added caching of URL so I wasn't hammering on site.
My findings after code listing
Modified code:
# Thread: https://python-forum.io/Thread-Still-learning-class-var
#---- National Weather System by Python:
from user_agent import generate_user_agent
from bs4 import BeautifulSoup
import requests
from pathlib import Path
import os
# Added cache capability, to turn off, call with cache=False
def get_page(url, cache=True):
home = Path('.')
print(home.resolve())
cachefilename = home / 'weather_main.html'
soup = None
if cache and cachefilename.exists():
with cachefilename.open('rb') as fp:
soup = BeautifulSoup(fp.read(), 'html.parser')
else:
headers = {'User-Agent': generate_user_agent(device_type='desktop', os=('mac', 'linux'))}
page_response = requests.get(url, timeout=5, headers=headers)
if page_response.status_code == 200:
if cache:
with cachefilename.open('wb') as fp:
fp.write(page_response.content)
soup = BeautifulSoup(page_response.content, 'html.parser')
if cache:
with cachefilename.open('wb') as fp:
fp.write(page_response.content)
else:
print('Unaable to fetch page. status_code: {}'.format(page_response.status_code))
return soup

current: Sunny
temp: None
Here's what I have found out
Note that temp-high is in current, but not temp-low
but in seven_day under 'Tonight', nut not 'Today'
It is inconistant, so you need to accommodate for this
** Note ** I have left all debugging statements in the code as you may want to use them for further debugging
Best way to view is to save to file:
python weather_prog_name.py > results.txt
