title: How to print pandas DataFrame without index
body: <p>I want to print the whole dataframe, but I don't want to print the index</p>
  
  <p>Besides, one column is datetime type, I just want to print time, not date.</p>
  
  <p>The dataframe looks like:</p>
  
  <pre><code>   User ID           Enter Time   Activity Number
  0      123  2014-07-08 00:09:00              1411
  1      123  2014-07-08 00:18:00               893
  2      123  2014-07-08 00:49:00              1041
  </code></pre>
  
  <p>I want it print as</p>
  
  <pre><code>User ID   Enter Time   Activity Number
  123         00:09:00              1411
  123         00:18:00               893
