I have this python code to extract the image src from an HTML website
listingid=[img['src'] for img in soup.select('[src]')]
Now would like to extract the values from the following output and store into a dictionary:
Any approach I can take to achieve this?
Im thinking if there is any syntax in python to take 14 characters before a specific suffix(like .jpg)
You can use negative indices in Python slices to count from the end. Since you say in the question you want 14 characters before a 4 character suffix, a simple s[-18:-4] would do.
With your code:
listingid = [img['src'] for img in soup.select('[src]')]
listingid = [s[-18:-4] for s in listingid]
or, in one statement:
listingid = [img['src'][-18:-4] for img in soup.select('[src]')]
If the number of characters is exactly the same use slicing for shorthand, if it differ I would recommend to try split() by pattern:
[i.get('src').split('_')[-1].split('.')[0] for i in soup.select('[src]')]
or using regex:
import re
[re.search('.*?([0-9]+)\.[a-zA-Z]+$',i.get('src')).group(1) for i in soup.select('[src]')]
from bs4 import BeautifulSoup
html = '''
<img src="img/katalog/honda-crv-4x2-2.0-at-2001_30082022103745.jpg">
<img src="img/katalog/mitsubishi-xpander-1.5-exceed-manual-2018_08072022134628.jpg">
'''
soup = BeautifulSoup(html)
[i.get('src').split('_')[-1].split('.')[0] for i in soup.select('[src]')]
['30082022103745', '08072022134628']
s[-18:-4]? Python slices can take negative indices to mean start from the end.
