body: <p>I tried typing 'abc' in the first block of id and 'cdef' in the second block of password. 
  However, the error code at the bottom comes up.</p>
  
  <pre><code>from selenium import webdriver
  driver.get('http://sugang.korea.ac.kr')
  </code></pre>
  
  <p>Added implicitly wait to prevent the code from executing before the page fully loads.</p>
  
  <p><code>driver.implicitly_wait(30)</code></p>

  <p><code>driver.find_element_by_name('id').send_keys('abc')</code>
  <code>driver.find_element_by_name('pw').send_keys('cdef')</code></p>
