That's one thing I forgot to move out of the loop before I sent it. I
was still working on the handling of m2 missing prior to that and put it
inside the loop for testing. Once moved should that be good to go?

Here's an update, will this work best or any other suggestions?
try:
import hashlib
m1 = hashlib.md5(path)
m2 = hashlib.sha256(path)
except:
import md5
m1 = md5.new(path)
m2 = None
f = open(path,"r")
while 1:
chunk = f.read(65536)
if not chunk:
break
m1.update(chunk)
md5checksum = m1.hexdigest()
if m2:
m2.update(chunk)
shachecksum = m2.hexdigest()
hexdigest() should only be called at end, outside
the loop. As it stands you're computing a checksum
for each chunk & resetting it
