title: Iterating through hash table giving out TypeError
body: <p>I have an array based Hash Table and whenever i try to iterate over it by :</p>
  
  <pre><code>for i in hash_table:
      val = hash_table[i]
  </code></pre>
  
  <p>an example of an output when i print the hash table would be:</p>
  
  <pre><code>(Alex:2),(Ryan:4),(Clara:6)
  </code></pre>
  
  <p>Whenever i try to iterate through it with the code I've written above, it is giving me a statement 'TypeError: 'int' object is not iterable'. I'm so confused about this and I'll appreciate any help on this.</p>
  
  <p>What I'm trying to do now is to print out only the values of each key in the hash table using the for loop above but the error message I'm constantly getting is always there.</p>
