url = 'https://www.python.org/'
reqs = requests.get(url)
soup = BeautifulSoup(reqs.text, 'lxml')

print(soup.find_all('h2')[0:4])
Sample Output:
First four h2 tags from the webpage python.org.: [<h2 class="widget-title"><span aria-hidden="true" class="icon-get-started"></span>Get Started</h2>, <h2 class="widget-title"><span aria-hidden="true" class="icon-download"></span>Download</h2>, <h2 class="widget-title"><span aria-hidden="true" class="icon-documentation"></span>Docs</h2>, <h2 class="widget-title"><span aria-hidden="true" class="icon-jobs"></span>Jobs</h2>]

Python: Tips of the Day
Find current directory and file's directory:
To get the full path to the directory a Python file is contained in, write this in that file:
import os dir_path = os.path.dirname(os.path.realpath(__file__))
(Note that the incantation above won't work if you've already used os.chdir() to change your current working directory, since the value of the __file__ constant is relative to the current working directory and is not changed by an os.chdir() call.)
To get the current working directory use
import os cwd = os.getcwd()
Documentation references for the modules, constants and functions used above:
- The os and os.path modules.
- The __file__ constant
- os.path.realpath(path) (returns "the canonical path of the specified filename, eliminating any symbolic links encountered in the path")
- os.path.dirname(path) (returns "the directory name of pathname path")
- os.getcwd() (returns "a string representing the current working directory")
- os.chdir(path) ("change the current working directory to path")
