ANSI is the standard for terminal control, so I usually code for
that, but put it in a separate module so that other terminals can
easily be accommodated.
Here is a short example:
import sys
import os
COLUMNS = int(os.environ.get('COLUMNS'))
LINES = int(os.environ.get('LINES'))
ESC = '\033'
CSI = ESC + "[" ## Command Sequence Introducer
CLS = CSI + "H" + CSI + "2J" ## Clear screen
NA = CSI + "0m" ## Clear text attributes
## set attributes
set_attr = CSI + "%sm"
set_bold = CSI + "1m"
set_ul = CSI + "4m"
set_rev = CSI + "7m"
def printat(row,col,arg=""):
sys.stdout.write( CSI + str(row) + ";" + str(col) + 'H' + str(arg))
### Demo:
row = 10
col = 30
print CLS
printat( row, col, set_bold + "Hello, world" )
printat( LINES, COLUMNS - 6, NA + "Goodbye" )
printat( 1, 1)
