Hi,
I'd like to read several strings by using 'input'.
These strings are separated by white space but I'd like to allow for
some quoting, e.g.
"Guido van" Rossum
should be split into 2 strings only
Now, a simple split doesn't work since it splits the quoted text as well.
Is there a simple way

Unfortunately, the string contains TeX commands which use lots of

The following example uses 2 German non-ascii characters.

The output of L[1] is correct, while the output of L shows up as

You could try a more recent version of Python like 2.6.5 and see if
you get the same sort of errors.
Try to run your application on a different machine if possible, to

Have you rebuild all Python packages you're using and which use an

txt = 'ea523a664dabaa4476d31226a1e3bab0'
c = crypt.encrypt(txt)
txt_plain=crypt.decrypt(c)
print txt_plain
Unfortunately, txt_plain differs from txt - why?
(Using MODE_ECB does work however)
What am I missing?
Many thanks for a hint,

s there some shorthand for this?

EQ.stdout is the filelike object you're looking for.
communicate() grabs entire output at once so don't use it.
Thanks a lot, I haven't found that in the official documentation.
Helmut.
That would be a documentation bug.

I could use StringIO.StringIO applied to EQ_output
but this reads all of the command's output into a big
string first.
On Unix/Linux a pipe is a file-like object after all,
so how to get hold of it.

Does this work, is it typical Python?

Yes, but that doesn't work here.

If you're referring to the source encoding declaration: No,
underscores have no effect. The specific

UnicodeEncodeError: 'ascii' codec can't encode characters in position 1-2:

So my system seems to be an ASCII system?
