Selenium PhantomJS click button inside class

Question

i have problem when i tried to click button using selenium with webdriver Phantonjs. My code is like this :

from selenium import webdriver

driver = webdriver.PhantomJS()
driver.set_window_size(1120, 550)
driver.get("https://www.instagram.com/nike/")
dt = driver.find_elements_by_class_name("a_8imhp _glz1g")

for i in dt:
    i.click()

driver.quit()

And the error is :

  File "test.py", line 8, in <module>
    dt = driver.find_elements_by_class_name("a_8imhp _glz1g")
  File "/usr/lib/python3.6/site-packages/selenium/webdriver/remote/webdriver.py", line 427, in find_elements_by_class_name
    return self.find_elements(by=By.CLASS_NAME, value=name)

You cannot pass more than one class name to find_elements_by_class_name(). You can try to pass single name, e.g.

driver.find_elements_by_class_name("a_8imhp")

or to use complex selectors, e.g. XPath or CSS selector

Just replace this

dt = driver.find_elements_by_class_name("a_8imhp _glz1g")

with this

dt = driver.find_elements_by_css_selector(".a_8imhp._glz1g")

or this

dt = driver.find_elements_by_xpath("//*[@class='a_8imhp _glz1g')
