Scrape candidates from HN thread https://news.ycombinator.com/item?id=35773705 into a csv file. You can view the candidate list here: https://github.com/subbu/ask-hn-candidate-list-chatgpt/blob/main/output.csv. Click on raw to copy the raw data.
You can generate json with this: https://github.com/subbu/ask-hn-candidate-list-chatgpt/blob/main/hn.py
Here is the whole transcript. User: write a python script to scrape https://news.ycombinator.com/item?id=35773705. Look for a div with class "comment" inside a div with class "default" and store it as a section. This section will have Location: Remote: Willing to relocate: Technologies: Résumé/CV: Email:
in separate lines. Identify these and store as a json object. Output all these json object in an array.
Assistant: To accomplish this task, you can use the requests and BeautifulSoup libraries in Python. If you haven't installed these libraries already, you can install them using the following commands:
pip install requests
pip install beautifulsoup4Here's a Python script to scrape the required data and store it in a JSON array:
import requests
from bs4 import BeautifulSoup
import json
url = "https://news.ycombinator.com/item?id=35773705"
response = requests.get(url)
soup = BeautifulSoup(response.content, "html.parser")
comments = soup.find_all("div", class_="default")
result = []
for comment in comments:
comment_section = comment.find("div", class_="comment")
if comment_section:
data = comment_section.get_text().strip().split("\n")
data_dict = {}
for line in data:
if line.startswith("Location:"):
data_dict["Location"] = line.split("Location:")[1].strip()
elif line.startswith("Remote:"):
data_dict["Remote"] = line.split("Remote:")[1].strip()
elif line.startswith("Willing to relocate:"):
data_dict["Willing to relocate"] = line.split("Willing to relocate:")[1].strip()
elif line.startswith("Technologies:"):
data_dict["Technologies"] = line.split("Technologies:")[1].strip()
elif line.startswith("Résumé/CV:"):
data_dict["Résumé/CV"] = line.split("Résumé/CV:")[1].strip()
elif line.startswith("Email:"):
data_dict["Email"] = line.split("Email:")[1].strip()
result.append(data_dict)
output = json.dumps(result, indent=2)
print(output)This script will output the scraped data as a JSON array, with each element containing the extracted information as key-value pairs. Please note that the script may not work if the target website's structure changes or if the website uses JavaScript to load the content. In such cases, you might need to use a headless browser like Selenium for web scraping.
User: its outputting an empty array. what can we do to debug and fix this?
Assistant: I apologize for the confusion. It seems that the target website structure might have changed or the content is loaded dynamically using JavaScript. Let's use the selenium library with a headless browser to load the page, and then use BeautifulSoup to parse the content.
First, install the required packages:
pip install selenium
pip install webdriver-managerNext, modify the script to use Selenium with a headless Chrome browser:
import json
from bs4 import BeautifulSoup
from selenium import webdriver
from webdriver_manager.chrome import ChromeDriverManager
url = "https://news.ycombinator.com/item?id=35773705"
options = webdriver.ChromeOptions()
options.add_argument('--headless')
options.add_argument('--disable-gpu')
options.add_argument('--no-sandbox')
options.add_argument('--disable-dev-shm-usage')
driver = webdriver.Chrome(ChromeDriverManager().install(), options=options)
driver.get(url)
soup = BeautifulSoup(driver.page_source, "html.parser")
driver.quit()
comments = soup.find_all("div", class_="default")
result = []
for comment in comments:
comment_section = comment.find("div", class_="comment")
if comment_section:
data = comment_section.get_text().strip().split("\n")
data_dict = {}
for line in data:
if line.startswith("Location:"):
data_dict["Location"] = line.split("Location:")[1].strip()
elif line.startswith("Remote:"):
data_dict["Remote"] = line.split("Remote:")[1].strip()
elif line.startswith("Willing to relocate:"):
data_dict["Willing to relocate"] = line.split("Willing to relocate:")[1].strip()
elif line.startswith("Technologies:"):
data_dict["Technologies"] = line.split("Technologies:")[1].strip()
elif line.startswith("Résumé/CV:"):
data_dict["Résumé/CV"] = line.split("Résumé/CV:")[1].strip()
elif line.startswith("Email:"):
data_dict["Email"] = line.split("Email:")[1].strip()
result.append(data_dict)
output = json.dumps(result, indent=2)
print(output)If you still get an empty array as output, it could be due to the target website's structure changes or the absence of the required data in the specified format. In that case, you may need to inspect the page source and update the script accordingly. You can use your browser's Developer Tools (usually accessible by pressing F12 or right-clicking and selecting "Inspect") to inspect the page structure and find the appropriate HTML elements and their classes.
User: still getting an empty error. Here is the snippet of what I am trying to scrape: [HTML snippet]
Assistant:
My apologies for the confusion. After analyzing the provided HTML snippet, it appears that the information is stored within <p> tags inside the comment section. Let's update the script accordingly to extract the information:
import json
from bs4 import BeautifulSoup
from selenium import webdriver
from webdriver_manager.chrome import ChromeDriverManager
url = "https://news.ycombinator.com/item?id=35773705"
options = webdriver.ChromeOptions()
options.add_argument('--headless')
options.add_argument('--disable-gpu')
options.add_argument('--no-sandbox')
options.add_argument('--disable-dev-shm-usage')
driver = webdriver.Chrome(ChromeDriverManager().install(), options=options)
driver.get(url)
soup = BeautifulSoup(driver.page_source, "html.parser")
driver.quit()
comments = soup.find_all("td", class_="default")
result = []
for comment in comments:
comment_section = comment.find("div", class_="comment")
if comment_section:
data = comment_section.find_all("p")
data_dict = {}
for line in data:
line_text = line.get_text().strip()
if line_text.startswith("Location:"):
data_dict["Location"] = line_text.split("Location:")[1].strip()
elif line_text.startswith("Remote:"):
data_dict["Remote"] = line_text.split("Remote:")[1].strip()
elif line_text.startswith("Willing to relocate:"):
data_dict["Willing to relocate"] = line_text.split("Willing to relocate:")[1].strip()
elif line_text.startswith("Technologies:"):
data_dict["Technologies"] = line_text.split("Technologies:")[1].strip()
elif line_text.startswith("Résumé/CV:"):
data_dict["Résumé/CV"] = line.find("a")["href"].strip()
elif line_text.startswith("Email:"):
data_dict["Email"] = line_text.split("Email:")[1].strip()
result.append(data_dict)
output = json.dumps(result, indent=2)
print(output)This updated script should now output the desired JSON array with the extracted information.
User: /Users/subbu/Downloads/hn.py:14: DeprecationWarning: executable_path has been deprecated, please pass in a Service object driver = webdriver.Chrome(ChromeDriverManager().install(), options=options) Traceback (most recent call last): File "/Users/subbu/Downloads/hn.py", line 41, in data_dict["Résumé/CV"] = line.find("a")["href"].strip() TypeError: 'NoneType' object is not subscriptable
Assistant:
Apologies for the oversight. It seems that the "Résumé/CV" line might not have a hyperlink in some cases, causing the script to throw an error. To handle this scenario, we can add a condition to check if the <a> tag exists before extracting the href attribute.
Regarding the deprecation warning, you can update the script to use the Service object for executable_path.
Here's the updated script:
import json
from bs4 import BeautifulSoup
from selenium import webdriver
from selenium.webdriver.chrome.service import Service
from webdriver_manager.chrome import ChromeDriverManager
url = "https://news.ycombinator.com/item?id=35773705"

options.add_argument('--disable-gpu')
options.add_argument('--no-sandbox')
options.add_argument('--disable-dev-shm-usage')
service = Service(ChromeDriverManager().install())
driver = webdriver.Chrome(service=service, options=options)
driver.get(url)
soup = BeautifulSoup(driver.page_source, "html.parser")
driver.quit()
comments = soup.find_all("td", class_="default")
result = []
for comment in comments:
comment_section = comment.find("div", class_="comment")
if comment_section:
data = comment_section.find_all("p")
data_dict = {}
for line in data:
line_text = line.get_text().strip()
if line_text.startswith("Location:"):
data_dict["Location"] = line_text.split("Location:")[1].strip()
elif line_text.startswith("Remote:"):
data_dict["Remote"] = line_text.split("Remote:")[1].strip()
elif line_text.startswith("Willing to relocate:"):
data_dict["Willing to relocate"] = line_text.split("Willing to relocate:")[1].strip()
elif line_text.startswith("Technologies:"):
data_dict["Technologies"] = line_text.split("Technologies:")[1].strip()
elif line_text.startswith("Résumé/CV:"):
resume_link = line.find("a")
if resume_link:
data_dict["Résumé/CV"] = resume_link["href"].strip()
else:
data_dict["Résumé/CV"] = line_text.split("Résumé/CV:")[1].strip()
elif line_text.startswith("Email:"):
data_dict["Email"] = line_text.split("Email:")[1].strip()
result.append(data_dict)
output = json.dumps(result, indent=2)
print(output)The updated script should now handle cases where the "Résumé/CV" line does not have a hyperlink and also removes the deprecation warning.
User: works. can you output the results into a csv file?
