That will tell you the terminal size at the time Python was started.
If the terminal size has changed while Python was running, those
environment variables will be wrong. You need to use the TIOCGWINSZ

Fine, indeed ! I've installed cs.ttyy.
I just don't understand the reason why it takes "fd" as an argument.

That gets the monitor size, i.e:

Hi there,
I want to know the number of columns of the terminal where python2 writes it's

In a terminal, I type

You can. But, the subprocess is going to inherit the value from the
Python program's environment, so it's just pointless complexity.

Ok, I think tracking these changes in real time is not worth the work to
be done using Python2.
I think at last I'll rewrite this (little) programe in Python3 in order to

I admit that none of my scripts is ambitious enough to try and track changes
in terminal size.
But still, Grant's post prompted me to reread the doc and source of

Hi there,
I want to know the number of columns of the terminal where python2 writes
it's outputs.
In a terminal, I type
$ echo $COLUMNS
100
But in Python, os.getenv("COLUMNS") gets nothing.
It gets nothing as well if I try to read the output of "echo $COLUMNS"
from a subprocess.
I feel that
