For those who have been getting the (AttributeError: module 'collections' has no attribute 'Callable'), add these two lines to your last import line to solve your issue. This was the solution I found after exploring several forums for this problem.
import collections
collections.Callable = collections.abc.Callable
Scraping Numbers from HTML using BeautifulSoup In this assignment you will write a Python program similar to http://www.py4e.com/code3/urllink2.py. The program will use urllib to read the HTML from the data files below, and parse the data, extracting numbers and compute the sum of the numbers in the file.
We provide two files for this assignment. One is a sample file where we give you the sum for your testing and the other is the actual data you need to process for the assignment.
Sample data: http://py4e-data.dr-chuck.net/comments_42.html (Sum=2553)
Actual data: http://py4e-data.dr-chuck.net/comments_1688329.html (Sum ends with 69)
You do not need to save these files to your folder since your program will read the data directly from the URL. Note: Each student will have a distinct data url for the assignment - so only use your own data url for analysis.
Data Format
The file is a table of names and comment counts. You can ignore most of the data in the file except for lines like the following:
...
Retrieve all of the anchor tags
tags = soup('a')
for tag in tags:
Look at the parts of a tag
print 'TAG:',tag
print 'URL:',tag.get('href', None)
print 'Contents:',tag.contents[0]
print 'Attrs:',tag.attrs
You need to adjust this code to look for span tags and pull out the text content of the span tag, convert them to integers and add them up to complete the assignment.
Sample Execution
$ python3 solution.py
Enter - http://py4e-data.dr-chuck.net/comments_42.html
Count 50
Sum 2...
Turning in the Assignment
Enter the sum from the actual data and your Python code below:
Sum:
(ends with 69)
can anyone solve this problem for me, i am so confuse
I work with PyCharm using Python 3.11 and encountered a similar issue, after installing bs4.
Implemented @Nikowos solution and it works! Thanks
Here is the way how you guys can solve this :
Working code below 👍
READ ME "":: Copy the actual Data url and run the file from the cmd/terminal and then paste the in terminal or CMD like so
#! /bin/python3
from urllib.request import urlopen
from bs4 import BeautifulSoup
import ssl
ctx = ssl.create_default_context()
ctx.check_hostname = False
ctx.verify_mode = ssl.CERT_NONE
leave the url empty for now. Paste the url after running the file in cmd or terminal.
url = input("")
html = urlopen(url, context=ctx).read()
soup = BeautifulSoup(html, "html.parser")
spans = soup('span')
numbers = []
for span in spans:
numbers.append(int(span.string))
print (sum(numbers))

This is the error I am getting can anybody help?
Notes Regarding the Use of BeautifulSoup
The sample code for this course and textbook examples use BeautifulSoup to parse HTML.
Using BeautifulSoup 4 with Python 3.10 or Python 3.11
Instructions for Windows 10:
-
pip install beautifulsoup4 (run this command)
-
if the bs4.zip file was downloaded, delete it
Instructions for MacOS:
-
pip3 install beautifulsoup4 (run this command)
-
if the bs4.zip file was downloaded or you have a bs4 folder, delete it
Using BeautifulSoup 3 (only for Python 3.8 or Python 3.9)
If you want use our samples "as is", download our Python 3 version of BeautifulSoup 3 from
http://www.py4e.com/code3/bs4.zip
You must unzip this into a "bs4" folder and have that folder as a sub-folder of the folder where you put our sample code like:
Hello I tried this for the same question:
#Scraping Numbers from HTML using BeautifulSoup
from urllib.request import urlopen
from bs4 import BeautifulSoup
import ssl
import re
Ignore SSL certificate errors
ctx = ssl.create_default_context()
ctx.check_hostname = False
ctx.verify_mode = ssl.CERT_NONE
url = input('Enter - ')
html = urlopen(url, context=ctx).read()
soup = BeautifulSoup(html, "html.parser")
Retrieve all of the anchor tags
counts = dict()
my_list = list()
tags = soup('span')
for tag in tags:
# Look at the parts of a tag
num = str(tag)
number = re.findall('[0-9]+', num)
if len(number) != 1:
continue
for integer in number:
integer = int(y)
my_list = append(integer)
counts[integer] = counts.get(integer, 0 ) + 1
print('Count ', counts)
#or you can say
#print('Count ', len(my_list))
print('Sum ', sum(my_list))

Thank you for your help, It works.
jai essaie sur vs code il y a un probleme trace back et maintenant sur jupyter toujours le resultat 0
uninstall the zip folder and the extracted folder of bs4 and install it using your command prompt by typing: -
pip install beautifulsoup4

this is the best way to answer. run it in terminal. thank you
Hi.. Can you please tell how you fixed the error. I've been getting the same error. Although bs4 folder is in the same directory as the python file.
