apply above script to multiple files add below on top -> def (defining functions of your own) -> def function_name():

sys.argv command line arguments -> passed to a python script

argv[0] is the script name

pat = sys.argv[1] #the pattern I search
time = 0
for p in sys.argv[2:]: #the srt files I search in
    print p
    tt=readsrt(p)

loop usage in python

for loop -> repeat n number of times of the code

while loop -> a condition is to be met, or if you want a piece of code to repeat forever, for example

more about for loop

nested loops

for x in xrange(1, 11):
    for y in xrange(1, 11):
        print ...

early exit

for x in xrange(3):
    if  x == 1:
        break

for else <source lang=python> for x in xrange(3):

   print x

else:

   print 'Final x = %d' %(x)

</python>
