Algorithm for getting time difference in Python

I want to ask you about getting the time difference in Python. Suppose my starting time is 11:30am and ending at 1:00pm. The difference would be 1:00pm-11:30am = 90 minutes. I am new to python. Are there existing algorithms to solve these kinds of problems? I need then for my scheduling algorithm problem.

Your response would be greatly appreciated. :)

If you cannot use datetime for some reason here is another solution.

def minutes(time):
    time, ampm = time[:-2], time[-2:]
    t = time.split(":")
    time = int(t[0]) * 60 + int(t[1])
    if ampm == "pm":
        time += 12 * 60
    return time

def timeDiff(string):
  start, end = string.split("-")

  diff = minutes(end) - minutes(start)

  if diff < 0:
      diff += 24 * 60
  return diff

timeDiff('11:30am-1:00pm')

Use the built-in datetime module:

from datetime import datetime

start = datetime(2014, 1, 22, 11, 30)
end = datetime(2014, 1, 22, 13, 00)

minutes = (end - start).total_seconds() / 60.0
