you need to import datetime module which contains method to convert string time to datetime object, once you have converted your time to datetime object , you can simply substract themtry using this,

import datetime
t1 = '11:19:04' 
t2 = '11:19:07'

t1_time=datetime.datetime.strptime(t1,"%H:%M:%S")
t2_time=datetime.datetime.strptime(t2,"%H:%M:%S")
print t2_time-t1_time
0:00:03

An alternative without the datetime module:

t1 = '11:19:04' 
t2 = '11:19:07'

def t2s(t):
    return sum(a*b for a, b in zip((int(x) for x in t.split(':')), (3600, 60, 1)))

print(t2s(t1) - t2s(t2))

It returns the difference as number of seconds.

Import datetime module:
Pass the striptime value to the String
Subtract the 't2' to 't1'

Demo :

import datetime

t1 = '11:19:04' 'From'
t2 = '11:19:07' 'Till'

t1_time = datetime.datetime.strptime(t1, "%H:%M:%S")
t2_time = datetime.datetime.strptime(t2, "%H:%M:%S")

print t2_time - t1_time
