Python Selenium get value from certain class - python-3.x

Question

I am trying to get the information in value=" " from this code.
As long as the class has the word orange in it, I want to store the value.
Expected result in this case is storing value "JKK-LKK" in a variable.
<input type="text" readonly="" class="form-control nl-forms-wp-orange" value="JKK-LKK" style="cursor: pointer; border-left-style: none;>
I have tried using
text = driver.find_elements_by_xpath("//*[contains(text(), 'nl-forms-wp-orange')]").get_attribute("value"))
But I get:
AttributeError: 'list' Object has no attribute 'get_attribute'.
I've also tried getText("value") but I get is not a valid Xpath expression.
If I try only using
driver.find_elements_by_xpath("//*[contains(text(), 'nl-forms-wp-orange')]")
The list becomes empty. So I feel like I might be missing some few other key pieces.
What might I be doing wrong?

Answer 1

To print the value of the value attribute i.e. JKK-LKK from the elements containing class attribute as nl-forms-wp-orange you can use either of the following Locator Strategies:
Using css_selector:
print(driver.find_element_by_css_selector("input.nl-forms-wp-orange").get_attribute("value"))
Using xpath:
print(driver.find_element_by_xpath("//input[contains(#class, 'nl-forms-wp-orange')]").get_attribute("value"))
Ideally you need to induce WebDriverWait for the visibility_of_element_located() and you can use either of the following Locator Strategies:
Using CSS_SELECTOR:
print(WebDriverWait(driver, 20).until(EC.visibility_of_element_located((By.CSS_SELECTOR, "input.nl-forms-wp-orange"))).get_attribute("value"))
Using XPATH:
print(WebDriverWait(driver, 20).until(EC.visibility_of_element_located((By.XPATH, "//input[contains(#class, 'nl-forms-wp-orange')]"))).get_attribute("value"))
Note : You have to add the following imports :
from selenium.webdriver.support.ui import WebDriverWait
from selenium.webdriver.common.by import By
from selenium.webdriver.support import expected_conditions as EC
