size should be a number of bytes to read. E.g.:
f.read(1000)
would read 1000 bytes. The size is optional:
f.read()
would read the entire file in one hit. Beware doing this on huge
files that could run you out of memory.

Not that I know of. Python is much the same whatever platform it
is on. The problem you see above would be exactly the same on
Linux, Windows or any other O/S.
Just remember to say what O/S when you post problems, just in
case it's relevant.
