– stockName never changes here so you don’t need to parse it at every
iteration. Could be moved before the for loop, and changed to stockName =
“AMAT” (edit: unless you need to parse other similar files, but still, it
would be best to do it only once)
– You need to know the timezone of your data : mktime uses local time but
if the timezone of your machine is different from the timezone of the data,
you will get wrong timestamps. Regardless unix timestamps are UTC, and
time.localtime() gives you the time in your machine’s timezone. This means
you can’t use the dateStamp field of your reformatted file in another
timezone… This can happen on a remote server, or when sharing files, so
you should add timezone info in dateStamp. You could also drop the field,
it seems redundant and useless anyway. This file is meant to be read by a
program, not a human.
– The output file should be opened once before the loop, and closed once
after the loop.
– You don’t need to read the whole thing all at once beforehand, but i
believe this issue has already been addressed… (edit: you can use
readline() as somebody suggested)

It’s interesting how versatile Python is in crunching data from many
different industries.
