Addressing the error message "TypeError: 'NoneType' object is not callable" while using a web scraper

Currently, I am in the process of developing a Python script that navigates to a specific website. The objective is to scan all the results of coins on the webpage, click on each result, and verify if there is a Telegram link available. If a Telegram link exists, it will be copied and appended to the print result. Otherwise, only the coin name will be printed. Unfortunately, I have encountered an error message stating: 'TypeError: 'NoneType' object is not callable', specifically on line 23 where element.click() is called. I'm uncertain about how to resolve this issue.

import requests
from bs4 import BeautifulSoup
from selenium import webdriver

# Setting up the WebDriver for browser simulation
driver = webdriver.Chrome()

# Sending a request to access the webpage
response = requests.get('https://www.coingecko.com/en/new-cryptocurrencies')

# Parsing the response
soup = BeautifulSoup(response.text, 'html.parser')

# Identifying all elements with the class "coin-name"
coin_elements = soup.find_all(class_='coin-name')

# Looping through the coin elements
for element in coin_elements:
  # Extracting text from the element (the coin name)
  coin_name = element.text
  
  # Simulating a click on the element
  element.click()
  
  # Allowing time for page loading
  time.sleep(2)
  
  # Parsing the content of the coin's page
  coin_soup = BeautifulSoup(driver.page_source, 'html.parser')
  
  # Locating the element containing the Telegram group link
  telegram_element = coin_soup.find('a', href=re.compile(r'^https://t\.me/'))
  
  # Checking if the element was found
  if telegram_element is not None:
    # Extracting the link from the element
    telegram_link = telegram_element['href']
    
    # Printing the coin name and corresponding link
    print(f'{coin_name}: {telegram_link}')
  else:
    # Displaying a message when the element is not found
    print(f'{coin_name}: No Telegram group found')

# Closing the WebDriver
driver.close()

Error Message:

line 23, in <module>
    element.click()
TypeError: 'NoneType' object is not callable

Answer №1

It's important to distinguish between selenium and BeautifulSoup. Using the code

coin_elements = soup.find_all(class_='coin-name')
will not provide you with a list of WebElements, making it impossible to use the click() function on them.

If you want to extract Telegram links from coin pages, there's no need to rely on selenium. You can achieve this using Python requests and BeautifulSoup.

Start by fetching all the URLs for the coins, then iterate through them to gather responses from each page and extract the telegram link.

Here is the code snippet:

import requests
from bs4 import BeautifulSoup
import requests
import re

response = requests.get('https://www.coingecko.com/en/new-cryptocurrencies')
soup = BeautifulSoup(response.text, 'html.parser')
coin_elements =["https://www.coingecko.com" + item['href'] for item in soup.select("table.sort a[href*='en/coins']")]
coin_elements_text =[item.text.strip() for item in soup.select("table.sort a[href*='en/coins']")]

for pageurl, coin_name in zip(coin_elements, coin_elements_text):
    r = requests.get(pageurl)
    coin_soup = BeautifulSoup(r.text, 'html.parser')
    telegram_element = coin_soup.select_one("a[rel='nofollow noopener'][href*='t.me']")
    try:
       telegram_link = telegram_element['href']
       print(f'{coin_name}: {telegram_link}')
    except:
       print(f'{coin_name}: No Telegram group found')

To choose clickable elements, utilize the find_elements_by_xpath method. Selenium exclusively allows datatypes specifically for the click action.

An example implementation would be:

elements = driver.find_elements_by_xpath('//*[@class='coin-name']')
for element in elements:
    element.click()

Keep in mind that based on your error message, a NoneType is being returned. This may indicate the need to examine the selectors more closely.
