How to Ignore the Error and Continue in Selenium?

This tutorial shows how to ignore (bypass) errors/exceptions in Selenium and continue processing.

Your problem is, you are scraping a website and the crawler stopped because of an exception.

Solution

You can use the try-except block to ignore the error and continue scraping in Selenium. Below is an example:

try:
   price = browser.find_element_by_id(id_).text
except:
   print("Price is not found.")
   price = "-"     # for dataframe

Another way. You can create a function to check if exists then continue processing. Below is another example:

from selenium import webdriver
browser = webdriver.Chrome()
import numpy as np
import pandas as pd

def check_if_exists(browser, id_):
    return len(browser.find_elements_by_css_selector("#{}".format(id_))) > 0

browser.get('https://www.yourwebsite.com')

id_ = 'priceblock_ourprice'
price =  browser.find_element_by_id(id_).text if check_if_exists(browser, id_) else "-"

df = pd.DataFrame([["info", "info", price]], columns=["Product", "Firm", "Price"])
df.to_csv('info.csv', encoding="utf-8", index=False, header=False)
df_final = pd.read_csv('info.csv')
df_final.head()
browser.quit()
