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="/"

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")
