Woops, yes, you have to call getblocks(f). Also, Heiko says you can't
use "return" to break out of the generator; I thought you could but
maybe I got co

This won't work. The following will:
def getblocks(f,blocksize=1024):
while True:
When I run the script, I get an error that the file object does not have
the attribute getblocks.
Did you mean this instead?
def getblocks(f, blocksize=1024):
while True:
s = f.read(blocksize)
if not s: return
yield s

This should work, but there is one hazard if the file is ver
A script I use for comparing files by MD5 sum uses the following
function, which you may find helps:
def getSum(self):
md5Sum = md5.new()
f = open(self.filename, 'rb')
for line in f:
md5Sum.update(line)
f.close()
return md5Sum

Actually, I think I got it but would like to confirm this looks right.
import md5
checksum = md5.new()
mfn = open(self.file_name, 'r')
for line in mfn.readlines():
checksum.update(line)
mfn.close()
cs = checksum.hexdigest()
print

the docs are your friend, use them. hint: first you eat, then you...

Good evening,
I need to generate checksums of a file, store the value in a variable,
and pass it along for later comparison.
The MD5 module would seem to do the trick but I'm sketchy on implementation.
The nearest I can see would be
import md5
m=md5.new()
contents = open(self.file_name,"rb").
