import numpy as n
g,p,w=n.array([[0]*3]*3),1,"-OX"
while True:
    for r in g: print(' '.join(w[x]for x in r))
    c,p=int(input(w[-p])),-p
    g[divmod(c-1,3)]=p
    s=n.concatenate((n.sum(g,axis=0),n.sum(g.T,axis=0),[sum(g.diagonal())],[sum(n.fliplr(g).diagonal())]))
    if e:=w[1]if 3 in s else w[2]if-3 in s else 0: exit(e+"wins")

Need Python 3.8 because walrus operator := on line 8 ( or until I find a shorter way to exit and determine if anyone wins)
