title: Python, Determine if a string should be converted into Int or Float
body: <p>I want to convert a string to the tightest possible datatype: int or float.</p>
  
  <p>I have two strings:</p>
  
  <pre><code>value1="0.80"     #this needs to be a float
  value2="1.00"     #this needs to be an integer.
  </code></pre>
  
  <p>How I can determine that value1 should be Float and value2 should be Integer in Python?</p>
