Hi,
I'm migrating my code to python3 now and find it hard to deal with python's
'str' and 'bytes' type. It's kind of painful.
One thing I find really confusing is that, writing to a socket requires
argument to be of type 'bytes'(otherwise python throw 'str does not support
buffer interface...' exception), while writing to a file requires argument to
be of type 'str'. Why is that? In standard UNIX interface, everything is file,
which mean that writing to a socket is the same as writing to a normal file.
This is true is python2. But thing doesn't seem to work in python 3.
Does anyone have idea why is this in python3 ?
In my understanding, writing to a file would requires that everything be
written byte by byte. So writing objects of type 'bytes' to socket makes sense.
But, how could python write to file using unicode(type 'str')? Does python
encode 'str'(Unicode) automatically before writing things to file? If it's
true, then why can't it do that automatic encoding when I trying to write a
'str' to socket ?
Regards,
Ruan
