a = "14:00"
b = "3:00"

def parseTime(s)
# split them at ":"
try:
split = s.split(':')
except:
raise ValueError("{0} is not in the right format.".format(s)

if split[0].isdigit():
# explicitly cast string val to an int to get an int.
i = int(split[0])
else:
raise TypeError("{0} is not an int.".format(split[0])

return i

if parseTime(a) > parseTime(b):
# do stuff.

string methods are cool: http://docs.python.org/library/stdtypes.html#string-
methods
