Not sure if python does some tricks here - but for me that seems to be
uneccesary shuffling around of data. Better do
for line in reve
Right now my code reads as follows:
infile=file(FileName)
for line in reversed(infile.readlines()): #Search from the bottom up
if int(line.split()[0]) == MyDate:
Data= float(line.split()[-1])
break
infile.close()
I have to read about 10,000 files, each with data. I'm l
Are you sure this is really slowing down your program? "Many hundreds
of lines" is not nearly enough to start Python breathing hard. I have
been really impressed with just how quickly Python is able to do file
input and processing, zipping through whole megs of data in just
seconds.
How are you
I just did strace on "tail -20 ". Apparently, it does seek to
the end and reads enough data to cover 20 lines. I guess it is
calculating this "size" by counting 20 new lines .You may try to do the
same thing.
Thanks,
Raghu.

I have a text file with many hundreds of lines of data. The data of
interest to me, however, resides at the bottom of the file, in the last
20 lines. Right now, I read the entire file and discard the stuff I
don't need. I'd like to speed up my program by reading only the last 20
lines. How do I do
