--------START--------
inp = file("input1.txt",'r') # input file is opened readonly
x = inp.readline() #read in the first line of the file
x = x.upper().split(None,5) #convert it to uppercase and split into 5
segments
print x #show the line as splitted and converted
print x[1] #show the second element
start = x[3].split(":") #split the minutes from the seconds
end = x[4].split(":") #split the minutes from the seconds
print "Start at:", start[0], "minutes and ", start[1], "seconds."
start_in_seconds = int(start[0])*60 + int(start[1]) #converts
minutes/seconds to seconds
print start_in_seconds , "seconds offset."
print "End at:", end[0],"minutes and",end[1], "seconds."
end_in_seconds = int(end[0])*60 + int(end[1])#converts minutes/seconds
to seconds
print end_in_seconds , "seconds offset."
totaltime = end_in_seconds - start_in_seconds #calculate the length of
the segment
print "Total time of segment in seconds:", totaltime
print "Total time of segment in minutes/seconds:", totaltime/60,
"minutes and", totaltime % 60, "seconds."
# ^^^ converts seconds back to minutes and seconds.
--------END--------
This should give you an excellent starting point.
