title: Joining Table/DataFrames with common Column in Python
body: <p>I have two DataFrames:</p>
  
  <pre><code>df1 = ['Date_Time',
      'Temp_1',
      'Latitude',
      'N_S',
      'Longitude',
      'E_W']
  
  df2 = ['Date_Time',
      'Year',
      'Month',
      'Day',
      'Hour',
      'Minute',
      'Seconds']
  </code></pre>
  
  <p>As You can see both DataFrames have <code>Date_Time</code> as a common column. I want to Join these two DataFrames by matching <code>Date_Time</code>.</p>
  
  <p>My current code is: <code>df.join(df2, on='Date_Time')</code>, but this is giving an error.</p>
