driver.find_element_by_xpath("//input[@id='credit-card-number']").send_keys(creditcardnumber)

Finding by Name

driver.find_element_by_name("credit-card-number").send_keys(creditcardnumber)

Finding by ID

I need help with locating the element for input.I get an error

As you are trying to send a character sequence within an <input> field sems to be a Credit Card Number and historically Credit Card Number resides within <iframes>.

So if the the desired elements are within an <iframe> so you have to:

• Induce WebDriverWait for the desired frame to be available and switch to it.
• Induce WebDriverWait for the desired element to be clickable.

• You can use the following solution:

  from selenium import webdriver
  from selenium.webdriver.common.by import By
  from selenium.webdriver.support.ui import WebDriverWait
  from selenium.webdriver.support import expected_conditions as EC
  
  options = webdriver.ChromeOptions() 
  options.add_argument("start-maximized")
  options.add_argument('disable-infobars')
  driver = webdriver.Chrome(chrome_options=options, executable_path=r'C:\Utility\BrowserDrivers\chromedriver.exe')
  driver.get("https://www.audiobooks.com/signup")
  WebDriverWait(driver, 20).until(EC.frame_to_be_available_and_switch_to_it((By.XPATH,"//iframe[@id='braintree-hosted-field-number']")))
  WebDriverWait(driver, 20).until(EC.element_to_be_clickable((By.XPATH, "//input[@class='number' and @id='credit-card-number']"))).send_keys("1234567890987654")

The error message

Unable to locate the element

usually because element generated by javascript, use WebDriverWait

inputCC = WebDriverWait(driver, 15).until(
    lambda driver: driver.find_element_by_xpath("//input[@id='credit-card-number']")
)
inputCC.send_keys(creditcardnumber)

other possibility is the element located in iframe
