Python - How can I open a file and specify the offset in bytes?

Question

I\'m writing a program that will parse an Apache log file periodically to log it\'s visitors, bandwidth usage, etc..

The problem is, I don\'t want to open the log an

Answer 1

log = open('myfile.log')
pos = open('pos.dat','w')
print log.readline()
pos.write(str(f.tell())
log.close()
pos.close()

log = open('myfile.log')
pos = open('pos.dat')
log.seek(int(pos.readline()))
print log.readline()

Of course you shouldn't use it like that - you should wrap the operations up in functions like save_position(myfile) and load_position(myfile), but the functionality is all there.
