Here's how I would probably do it:
Use 2 dicts, one for the start time of each user, and the other for the
total elapsed time of each user.
For each line extract the user name, date/time and whether the user is
starting, finishing, etc.
When a user starts, save the info in the first dict, and when a user
finishes, calculate the elapsed time and add it to the total for that
user.
The date/time can be parsed by the time or datetime module.
