title: Python - Convert datetime column into seconds
body: <p>I have a date column (called 'Time') which contains days/hours/mins etc (timedelta). I have created a new column in my dataframe and I want to convert the 'Time' column into seconds and put it in the new column for each row.</p>
  
  <p>Does anyone have any pointers? All I can find on the internet is how to convert your column, not create a new column and convert another one.</p>
  
  <p>Thank you in advance!</p>
