title: python 3.5 printing formated float number
body: <p>I've found something interesting with my python3.5 </p>
  
  <p>So this is the code</p>
  
  <pre><code>previous = 0.1234567891011121314
  now = 2.98764627181
  
  print("Before: {0:.15f}".format(float(previous)))
  print("Now: {0:.15f}".format(float(now)))
  
  
  print(" Before:{0:.15f} Now:{0:.15f} ".format(float(previous), float(now)))
  </code></pre>
  
  <p>and this is the result </p>
  
  <pre><code>Before: 0.123456789101112
  Now: 2.987646271810000
  Before:0.123456789101112 Now:0.123456789101112
  </code></pre>
  
  <p>So when I want to print them with one single print and format function
  python3.5 seems to not able to handle it. Am I doing something wrong?</p>
