Try something like this:
import urllib.request
from bs4 import BeautifulSoup
theurl = "https://www.kickstarter.com/discover/advanced?category_id=16&woe_id=23424829&sort=magic&seed=2449064&page=1"
thepage = urllib.request.urlopen(theurl)
soup = BeautifulSoup(thepage)
project_href = [i['href'] for i in soup.find_all('a', href=True)]
print(project_href)
href. , href # . #.
project_href = [i['href'] for i in soup.find_all('a', href=True) if i['href'] != "#"]
, /discover?ref=nav, , , .
EDIT:
, :
soup = BeautifulSoup(thepage)
for i in soup.find_all('div', attrs={'class' : 'project-card-content'}):
print(i.a['href'])
