problem is, I'm assuming that the 'open' command buffers the data
somewhere and that data is being wiped out by the CSV module but
surely this shouldn't happen.

Try using sys.stdin.buffer instead of sys.stdin. It gives you bytes

Hi!
I need to create a pretty complex class at runtime. something like
this one:
(note: "" means that the number of attributes can be variable)
class VirtualUserLimitForm(ModelForm):
swap_limit = forms.CharField(max_length=100,
initial=monitor1.default_limit)
memory_limit = forms.Char
naries ..), but I
have not yet clear whether this will be usefull for create the
__init__ function at runtime too. Any clue on this?
Many, many thanks!! :)

`==` has a higher precedence than `not` so Python interprets it as::
(1 == not) 0
This works::
>>>
d(aline[:-1].split(None, 1))
That works too if md5sum opened the files in binary mode which is the
default on Windows. The filename is prefixed with a '*' then, leaving
just one space between checksum and filename.

/ it'd be nicer if i could just select a proper locale
It uses the locale of the system. If *your* systems locale is configured
to use ',' as separator for grouping, then it should be used by
`locale.format()`.

of handling multiple

Still incomplete. You don't map an index to a buffer in that code. What
is getBuf() doing?

A lot of redundant code. Try something like the following instead of the
``elif`` sequence::
name_part = ['prefix', 'given', 'surname', 'suffix', 'patronym', 'toponym']
for row in result:
query = 'update names set %s=%%s where name_id=%%s' % name_part[row[2]-1]
sql.execute(query, (row[4], row[1]))
sql.commit()
