title: Create folder based on date
body: <p>I am a newbie in python and building a scraper using webdriver. I am trying to take screenshots from a website. Its taking the screenshot fine but saving it in the root folder. My code is below</p>
  
  <pre><code>print ("step is === "+str(scrollStep))
  for i in range(1, max_sreenshots):
      driver.save_screenshot("./screenshot_"+str(i)+".png")
      driver.execute_script("window.scrollTo("+str(scrollStart)+", "+str(scrollEnd)+");")
      scrollStart = scrollStart + scrollStep
      scrollEnd = scrollEnd + scrollStep
  </code></pre>
  
  <p>As you can see, its only creating files. I want it to save it in folder by date. How can I achieve that.
  Thank you</p>
