Python Web Scraping: Extract and display all the image links from en.wikipedia.org/wiki/Peter_Jeffrey_(RAAF_officer)
Python Web Scraping: Exercise-8 with Solution
Write a Python program to extract and display all the image links from en.wikipedia.org/wiki/Peter_Jeffrey_(RAAF_officer).
Sample Solution:
Python Code:
from urllib.request import urlopen
from bs4 import BeautifulSoup
import re
html = urlopen('https://en.wikipedia.org/wiki/Peter_Jeffrey_(RAAF_officer)')
bs = BeautifulSoup(html, 'html.parser')
images = bs.find_all('img', {'src':re.compile('.jpg')})
for image in images:
print(image['src']+'\n')
Sample Output:
//upload.wikimedia.org/wikipedia/commons/thumb/a/af/NlaJeffrey1942-43.jpg/220px-NlaJeffrey1942-43.jpg //upload.wikimedia.org/wikipedia/commons/thumb/c/c5/008315JeffreyTurnbull1941.jpg/260px-008315JeffreyTurnbull1941.jpg //upload.wikimedia.org/wikipedia/commons/e/ea/021807CameronJeffrey1941.jpg //upload.wikimedia.org/wikipedia/commons/thumb/9/92/AC0072JeffreyTruscottKittyhawks1942.jpg/280px-AC0072JeffreyTruscottKittyhawks1942.jpg //upload.wikimedia.org/wikipedia/commons/thumb/2/26/VIC1689Jeffrey1945.jpg/280px-VIC1689Jeffrey1945.jpg

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")
