BeautifulSoup: Exercise-10 with Solution
Write a Python program to find all the link tags and list the first ten from the webpage python.org.
Sample Solution:
Python Code:
import requests
from bs4 import BeautifulSoup
url = 'https://www.python.org/'
reqs = requests.get(url)
soup = BeautifulSoup(reqs.text, 'lxml')
print("First four h2 tags from the webpage python.org.:")
print(soup.find_all('a')[0:10])
Sample Output:
First four h2 tags from the webpage python.org.: [<a href="#content" title="Skip to content">Skip to content</a>, <a aria-hidden="true" class="jump-link" href="#python-network" id="close-python-network"> <span aria-hidden="true" class="icon-arrow-down"><span>▼</span></span> Close </a>, <a class="current_item selectedcurrent_branch selected" href="/" title="The Python Programming Language">Python</a>, <a href="/psf-landing/" title="The Python Software Foundation">PSF</a>, <a href="https://docs.python.org" title="Python Documentation">Docs</a>, <a href="https://pypi.python.org/" title="Python Package Index">PyPI</a>, <a href="/jobs/" title="Python Job Board">Jobs</a>, <a href="/community/" title="Python Community">Community</a>, <a aria-hidden="true" class="jump-link" href="#top" id="python-network"> <span aria-hidden="true" class="icon-arrow-up"><span>▲</span></span> The Python Network </a>, <a href="/"><img alt="python™" class="python-logo" src="/static/img/python-logo.png"/></a>]

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")
