get the terminal's size

[Alex Ternaute]

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 I'm missing something but what ?

Looking on the internet for a hint, I see that python3 has an  
os.get_terminal_size(). 
Please, is there something similar for python2 ?

Cheers
