Thanks to everyone for answers..
*but*, if you want to add more logic in the setters, you could want to add two
extra methods :
def _setsquare(self, v) :
# some extra logic here
self._square = s
def fsetsquare(self,s):
self

Sending and receiving little messages (~100 char) works fine. However,

Hi guys
I do
os.system('ls &> e')
On one linux machine it emits ls output to the file e as expected.
On another linux machine it emits ls to the standard output, and
nothing to e!
Both machines run Fedora linux.
The command "ls &> e" entered at the shell (no python) behaves ok on
both machines.
I tried under Linux... same problem.
So... it may comes from my little lines of code... or from my GPS.

Hello everyone,
I try to set two properties, "value" and "square" in the following code,

^^
or just:
self._value = val
