python - Print and update a matrix in-place -


i have matrix represented list of lists (but can change representation if help). updating matrix program runs. have matrix displayed on screen in standard way. like

enter image description here

i display update program runs.

for example,

def updatematrix(): #change entries in matrix  = [[3,2,3],[1,2,1],[2,8,6]] while(true):     updatematrix()     display(a) #this ideally change display in place.

what way of doing this? (in fact changing entire columns , rows , want make changed row/column in different color.)

i happy use free libraries might useful.

i'd suggeest using curses library, part of standard python libraries http://docs.python.org/2/library/curses.html

i've included bit of hacked example 

import curses import time  mywindow = curses.initscr()  matrix = [[3,2,3],[1,2,1],[2,8,6]]  def updatematrix(m):     m[1][1] = m[1][1] * 2     return m  def getmarixstring(m):     x = ''     row in m:         x += ' '.join(str(item) item in row)         x += "\n"     return x  z = 10 while z > 1:     matrix = updatematrix(matrix)     mywindow.addstr(0,0, getmarixstring(matrix))     mywindow.refresh()     z -= 1     time.sleep(3)  curses.endwin() quit()
