Selenium how to find an image by src that contain a string

Question

I don't find an image on page with selenium. My script is in python.

    try:
        is_captcha = driver.find_element_by_css_selector("img[src*='validation']")
        if is_captcha:
            print("CAPTCHA FOUND!")
    except:
        try:
            is_captcha = driver.find_element_by_css_selector("[src*='validation']")
            if is_captcha:
                print("CAPTCHA FOUND!")
        except:
            print ("No catpcha form for {}".format(link_hyip))

The HTML code where my image is :

<td class="menutxt"><img src="?a=show_validation_image&amp;PHPSESSID=u020264onvkgu0fsl9b94lk1v1&amp;rand=1901750303"></td>

I got this error :

no such element: Unable to locate element: {"method":"css selector","selector":"[src*='validation']"}
  (Session info: chrome=76.0.3809.132)

thank for you help !

Why are you looking for a css-selector? I think you should use xpath and search the image source... Something like driver.find_element_by_xpath("//img[contains(@src, 'validation')]"). — nostradamus

How about XPATH? driver.find_element_by_css_selector("//img[contains(@src, 'a=show_validation')]"). — Toan Quoc Ho

@nostradamus i got this error with the xpath :( no such element: Unable to locate element: {"method":"xpath","selector":"//img[contains(@src, 'validation')]"} — Valentin Garreau

Use WebdriverWait and visibility_of_element_located and the below xpath.

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

driver = webdriver.Chrome()
driver.get('https://www.lanysoft.biz/?a=support')
try:
  is_captcha =WebDriverWait(driver,10).until(EC.visibility_of_element_located((By.XPATH,"//form[@name='loginform']//img[contains(@src,'show_validation')]"))) 
  if is_captcha:
    print("CAPTCHA FOUND!")
except:
    print('recapcha not found')
