body: <p>I have a problem with making an Instagram-like bot with Selenium.
  I am trying to write code that passes a picture if liked, but it is not working.
  Here is my code: </p>
  
  <pre><code>    def Like_photoTags_and_commnet(self,hashtag,comment):
  
      driver=self.driver
      driver.get("https://www.instagram.com/explore/tags/" + hashtag + "/")
      time.sleep(2)
  
      pic_hrefs = []
      for i in range(1,3):
          driver.execute_script("window.scrollTo(0,document.scrollHeight);")
          time.sleep(2)
      #searching for pictures link
          hrefs_in_view = driver.find_elements_by_tag_name('a')
          # finding relevant hrefs
          hrefs_in_view = [elem.get_attribute('href') for elem in hrefs_in_view
                           if '.com/p/' in elem.get_attribute('href')]
          # building list of unique photos
          [pic_hrefs.append(href) for href in hrefs_in_view if href not in pic_hrefs]
          print("Check: pic href length " + str(len(pic_hrefs)))
  
          for pics in pic_hrefs:
              driver.get(pics)
              #if picture liked then continue
              if driver.find_element_by_xpath("//button/span[@aria-label='UnLike']"):
                  continue
              else:
                  driver.find_element_by_xpath("//button/span[@aria-label='Like']").click()
  
              if comment in driver.page_source:
                  continue
              else:
                  driver.find_element_by_class_name("Ypffh").click()
                  for letter in comment:
                      driver.find_element_by_class_name("Ypffh").send_keys(letter)
                      time.sleep(random.randint(1,2))
                  driver.find_element_by_class_name("Ypffh").send_keys(Keys.ENTER)
                  time.sleep(5)
