Clicked button doesn’t really function by Selenium Python

I’ve been trying to click a button that downloads a CSV file from “https://mol.org/regions/?regiontype=countries”. I’m sure that I’ve selected the button, as I can print the text written on it, but whenever I try to .click() it, it doesn’t download the file. Are there any additional steps needed to operate the function bound to the button? Thank you in advance.

PS : The button works manually.

Here is the driver code I used :

with webdriver as driver:
    driver.maximize_window()
    driver.implicitly_wait(30)
    driver.get(url)
    driver.maximize_window()
    wait = WebDriverWait(driver, 10)
    wait.until(EC.element_to_be_clickable((By.CSS_SELECTOR, search_bar_CSS_Selector))).send_keys(search_query+Keys.RETURN)
    driver.find_element_by_css_selector(download_button_CSS_Selector).click()
    print(driver.find_element_by_css_selector(download_button_CSS_Selector).text)
    driver.close()

You can see that I actually print the button text & can access it, but the .click() is not working as expected.

Variables :

search_query = 'Egypt'
search_bar_CSS_Selector = "input[placeholder='Filter Political boundaries']"
download_button_CSS_Selector = "button[ng-click ='initiateDownload()']"

Answer

Your css selector looks perfect, but I think it's a page loading issue. So I tried that with an explicit wait command (check below) and it seems working fine.

Sample code :

so instead of this :

driver.find_element_by_css_selector(download_button_CSS_Selector).click()

use this :

wait.until(EC.element_to_be_clickable((By.CSS_SELECTOR, "button[ng-click ='initiateDownload()']"))).click()

Update 1 :

driver.get("https://mol.org/regions/?regiontype=countries")
driver.maximize_window()
wait = WebDriverWait(driver, 10)
wait.until(EC.element_to_be_clickable((By.CSS_SELECTOR, "input[placeholder='Filter Political boundaries']"))).send_keys('Egypt'+Keys.RETURN)
wait.until(EC.element_to_be_clickable((By.CSS_SELECTOR, "button[ng-click ='initiateDownload()']"))).click()
