title: keep getting typeerror: unsupported operand type(s) for +: 'int' and 'str' in python
body: <p>Taking a beginning Python class and was asked to debug a small program. Have all of it done except this one part</p>
  <pre><code>a = 2             # Declare a variable with a value, 2
  b = 19             # Declare a variable with a value, 19               
  c = a + (&quot;.&quot;) + b       # Concatanate strings, a, &quot;.&quot;, and b 
  print (type(c))     # print c's type
  print (c)           # print c
  </code></pre>
  <p>Expected output</p>
  <pre><code>class&lt;str&gt;
  2.19
  </code></pre>
  <p>can't figure out this decimal point I know it has something to do with that.</p>
