selenium remotewebdriver example java- python selenium xpath/css selector

Question

I am trying to select for a particular information using xpath or css selector. But I keep on getting error messages. Can someone help with seeing what's wrong here?

This is part of my code

output = driver.find_element_by_xpath("//td[@class_= 'sku']")

print(output)

Using the modifications give below, I am obtaining this error message:

Traceback (most recent call last):

This is the code that I have written:

from selenium.webdriver.support.ui import WebDriverWait

from selenium import web

driverfrom selenium.common.exceptions import TimeoutException

from selenium.webdriver.support import expected_conditions as EC

url = "http://www.google.com"

#cas = "1300746-79-5"

cas = "100-44-7"

driver = webdriver.Firefox()

driver.get(url)

inputElement = driver.find_element_by_name("Query")

inputElement.send_keys(cas)

inputElement.submit()

pricing_link = driver.find_element_by_css_selector("li.priceValue a")

pricing_link.click()

output = driver.find_element_by_xpath("//td[@class='sku']/p") 

print(output)

driver.quit()

This is a timing issue, where you need to use WebDriverWait to wait for table loading.

# XPath to select <p> inside <td> with class name 'sku'

outputs_by_xpath = WebDriverWait(driver, 10).until(

    lambda driver : driver.find_elements_by_xpath(".//td[@class='sku']/p

")

)

# or CSS selector

outputs_by_css = WebDriverWait(driver, 10).until(

    lambda driver : driver.find_elements_by_css_selector("td.sku > p

")

)

for output in outputs_by_xpath:

    print(output.text)

print("\n")

for output in outputs_by_css:

    print(output.text)

Output:
