title: A good way to store date-based data using python?
body: <p>I'm working on a little pet project and I want to store data based on date, preferably using python. </p>
  
  <p>The data to be stored is basically activity logs, i.e. you did a number of activities for some duration each for some date. I expect the number of 'activities' to be in the range 0 - 100 for each date.</p>
  
  <p>I want to store the data using a as close to 'standard' way as possible. I'm somewhat hesitant to what format I should use. </p>
  
  <p>What's a good way to store this type of data, and how can that be done using python (third party libraries and/or services included)?</p>
  
  <p>Edit: I'm fully aware that there's a ton of different ways you can accomplish this, what I'm looking for is the most appropriate way to accomplish it.</p>
