Using Xterm control sequence
import sys
sys.stdout.write(b'33]0;title you wanta')
sys.stdout.flush()
will do the job but you can get fancier
in python 3.x
print('33]0;title you wanta', end='')
sys.stdout.flush()
or in python 3.3 or better
print('33]0;title you wanta', end='', flush=True)
or
sys.stdout.buffer.write(b'33]0;title you wanta')
sys.stdout.buffer.flush()
