The following line in my code is failing because sys.stdin.encod ing is
Null. This has only started happening since I started working with
Pydef in Eclipse SDK. Any ideas?
uni=unicode(wor d,sys.stdin.enc oding)

I'll guess you mean None rather than Null.

You could give it a fallback value:
uni = unicode(word, sys.stdin.encod ing or sys.getdefaulte ncoding())
or even just:
uni = unicode(word, sys.stdin.encod ing or 'ascii')
which should be the same in all reasonable universes (although I did get
bitten recently when someone had changed the default encoding in a system).

Thanks for your help. The problem now is that I cant enter the Swedish
characters åöä etc without getting the following error -
Enter wordPåe
Traceback (most recent call last):
File "C:\Documen ts and Settings\worksp ace\simple\src\ main.py", line

uni=unicode(wor d,sys.stdin.enc oding or sys.getdefaulte ncoding())
UnicodeDecodeEr ror: 'ascii' codec can't decode byte 0xe5 in position 1:

The call to sys.getdefaulte ncoding() returns ascii. Since I can enter
the characters åöä on the command line in Pydef/Eclipse doesn't that
mean that the stdin is not ascii? What should I do?
Thanks again,

That's a problem with pydev, where the standard machinery to determine
the terminal's encoding fail.
I have no idea yet how to fix this.

I think that depends on what sort of script you are writing.
If it is just something for personal use on a single machine, or if you
know that the same encoding is going to be used on all systems where you
have this problem, then you could hardwire the encoding to whatever it
should be (maybe 'latin1').
If it is to be used across a variety of systems with different encodings
then you'll have to figure out some way to find the correct encoding.

Yeah I'm only learning python so I think I can go with latin1.

The workaround in your case is:
in the beginning of your program:
import sys
if hasattr(sys.std in, 'encoding'):
console_encodin g = sys.stdin.encod ing
else:
import locale
locale_name, console_encodin g = locale.getdefau ltlocale()
and later:
uni = unicode(word, console_encodin g)
But don't think it's portable, if you use other IDE or OS, it may not
work. It would be better if PyDev implemented sys.stdin.encod ing

Environmental variable TERMENCODING ? Heck, maybe this will catch on
and will be used by other languages, libraries, terminals, etc. It's
not really Python only problem.

I also considered environment variables. This can likely be made
available only in 2.6, though.
Plus, in the Eclipse case, we can't know for sure that stdout
really goes to the terminal - as it is just a pipe file descriptor
(Java is not capable of managing a full pseudo-terminal).

I want to read and write unicode on stdin and stdout. I can't seem to
find any way to force sys.stdin.encoding and sys.stdout.encoding to be
utf-8, so I've got the following workaround:
import codecs, sys
out = codecs.getwriter("utf-8")(sys.stdout)
def tricky(): return sys.stdin.readline().decode("utf-8").
That is, I wrap sys.stdout in a utf-8 writer and I read utf-8 input

Hi folks.
I'm somewhat new to *nix programming and just ran into a problem. I have
to take user input from the terminal but like to constrain that to some
rules given, i.e. "numbers only" or "alphanumeric only" etc.
scanf would do, but I don't like the fact that wrong ('disallowed')
characters are visible and all that stuff. For that I need unbuffered
input. Since there seems to be no atomic function to do that I tried to
fiddle around...
