title: Counting capitalized or non-capitalize in dictionary
body: <p>So I have this dictionary, </p>
  
  <pre><code>word_counts = {'Two':2, 'one':3, 'Forks.':1, 'knife.':2, 
  'glasses.':2, 'plate.':1, 'Naptkin.':1, 'his':2}
  </code></pre>
  
  <p>And i need to compute how to how many are capitalized and non-capitalized. I know I need to do this by getting the keys of the dictionary and loop through them all, but I'm having trouble. Please help. Thank you!</p>
  
  <p>Tried to use counter variables with for loops and isupper() and islower() but its not working. If you haver better ways please let me know!</p>
  
  <pre><code>#What ive done so far
  word_counts = {'Two':2, 'one':3, 'Forks.':1, 'knife.':2, 
      'glasses.':2, 'plate.':1, 'Naptkin.':1, 'his':2}
  
  for word, occurence in words:
          upper_counter = 0
          lower_counter = 0
          for word in word_counts.items():
              if word.isupper():
                  upper_counter += 1
              elif word_islower():
                  lower_counter += 1
  </code></pre>
