AttributeError: 'WebElement' object has no attribute 'extract_first' - python-3.x

Question

I am trying to run the script below to extract the tags from a webpage and save them into a csv file.
In details, I want to extract the tags associated to a class name.
However, I come across this error: AttributeError:
'WebElement' object has no attribute 'extract_first'.
The script is the following:
import csv
from selenium import webdriver
from time import sleep
from parsel import Selector
from selenium.webdriver.common.keys import Keys
from collections import defaultdict
from selenium.webdriver.support.select import Select
####### reading from the input file ##########
columns = defaultdict(list) # each value in each column is appended to a list
# get the list of keywords from the csv file
with open('query.csv', 'r') as csvfile:
reader = csv.DictReader(csvfile) # read rows into a dictionary format
for row in reader: # read a row as {column1: value1, column2: value2,...}
for (k, v) in row.items(): # go over each column name and value
columns[k].append(v) # append the value into the appropriate list
# the list containing all of the keywords
search_query_list = columns['Keyword']
########## start scraping ###############
rb_results = []
# create a driver and let it open google chrome
driver = webdriver.Chrome("chromedriver")
# get website
driver.get('https://www.redbubble.com/')
sleep(0.5)
for i in range(len(search_query_list)):
next_query = search_query_list[i]
# get RB website
driver.get('https://www.redbubble.com/')
# get the search by its id
search_bar = driver.find_element_by_name("query")
sleep(0.5)
# enter the query to the search bar
search_bar.send_keys(next_query)
# press enter
search_bar.send_keys(Keys.RETURN)
sleep(1)
# from parsel's selector get the page source
sel1 = Selector(text=driver.page_source)
sleep(0.5)
# get first shirt //
continue_link = driver.find_element_by_class_name('shared-components-ShopSearchSkeleton-ShopSearchSkeleton__composedComponentWrapper--1s_CI').click()
sleep(1)
sel2 = Selector(text=driver.page_source)
sleep(0.5)
################## get TAGS ###############
# Check tags for all products
try:
# get the tags for the search query
tags_rb = driver.find_element_by_class_name("shared-components-Tags-Tags__listContent--oLdDf").extract_first()
tags_rb = str(tags_rb)
# if number of products is found print it and search for the prime
# print the number of products found
if tags_rb == None:
rb_results.append("0")
else:
#rb_results = str(tags_rb)
rb_results.append(tags_rb)
except ValueError:
pass
#except:
#rb_results.append("errore")
###### writing part ########
with open ("rb_results.csv","w", newline='') as resultFile:
writer = csv.DictWriter(resultFile, fieldnames=["Rb Results"],delimiter='\t')
writer.writeheader()
writer.writerows({'Rb Results': item} for item in rb_results)
resultFile.close()
Any ideas about how to fix it and extract the text of shared-components-Tags-Tags__listContent--oLdDf ? Many thanks!!!

Answer 1

If I right understand, you want an element text. So you can do it like this:
replace:
tags_rb = driver.find_element_by_class_name("shared-components-Tags-Tags__listContent--oLdDf").extract_first()
with:
tags_rb = driver.find_element_by_class_name("shared-components-Tags-Tags__listContent--oLdDf").text
You are getting this error:
'WebElement' object has no attribute 'extract_first'.
because WebElement does not have method .extract_first().
PS: you don't need this:
tags_rb = str(tags_rb)
The code block to replace is:
# Check tags for all products
try:
# get the tags for the search query
tags_rb = driver.find_element_by_class_name("shared-components-Tags-Tags__listContent--oLdDf").text # get text
# tags_rb = str(tags_rb) no need in this line
# if number of products is found print it and search for the prime
# print the number of products found
if tags_rb == None:
rb_results.append("0")
else:
#rb_results = str(tags_rb)
rb_results.append(tags_rb)
except ValueError:
pass
