Python and Selenium To “execute_script” to solve “ElementNotVisibleException”

Alternative option would be to make the click() inside execute_script():

# wait for element to become present
wait = WebDriverWait(driver, 10)
checkbox = wait.until(EC.presence_of_element_located((By.NAME, "keywords_here")))

driver.execute_script("arguments[0].click();", checkbox)

where EC is imported as:

from selenium.webdriver.support import expected_conditions as EC

---

Alternatively and as an another shot in the dark, you can use the element_to_be_clickable Expected Condition and perform the click in a usual way:

wait = WebDriverWait(driver, 10)
checkbox = wait.until(EC.element_to_be_clickable((By.NAME, "keywords_here")))

checkbox.click()
