Tetris en un par líneas de código
Este es otro de los post reencauchados de mi antiguo blog.
Se trata de un tetris programado en python, son tan sólo 15 líneas de código, cada línea no contiene más de 80 caracteres:
import random,pygame;R=range;L=len;W=10;Q=H=20;P=pygame;G=255;v=lambda b:['0'*W
]*(H-L(b))+b;a=p=x=y=c=d=0;D=P.display;T=P.USEREVENT;m=lambda i,j:j-y in R(L(p)
)and i-x in R(L(p[0]))and'0'!=p[j-y][i-x]and`d+1`or b[j][i];S=D.set_mode((W*Q,H
*Q));k=lambda p,x,y:1-max(p[i][j]!='0'and(y+i>=H or x+j<0or x+j>=W or’0?!=b[i+y
][j+x])for j in R(L(p[0]))for i in R(L(p)));n=E=b=v([]);P.time.set_timer(T,100)
exec(”while E!=P.QUIT:\n E=P.event.wait().type;K=P.key.get_pressed()\n if n:d=”
“random.randrange(7);q=’111?;p=[[’1?*4],[’010?,q],[’110?,’011?],[’011?,’110?],”
“[q,’100?],[’11?,’11?],[q,’001?]][d];x=W/2-L(p[0])/2;y=n=0\n if E==T:\n [P.dr”
“aw.rect(S,[(h,g,f)for f in(0,G)for g in(0,G)for h in(0,G)][int(m(i/H,i%H))],(”
“(i/H*Q,i%H*Q),(Q,Q)))for i in R(W*H)];t='’.join;z=[t([p[L(p)-1-i][j]for i in ”
“R(L(p))])for j in R(L(p[0]))];p,x,y=[p,z][K[P.K_UP]*k(z,x,y)],x-(K[P.K_LEFT]*”
“k(p,x-1,y))+(K[P.K_RIGHT]*k(p,x+1,y)),y+(K[P.K_DOWN]*k(p,x,y+1));B=[t([m(i,j)”
“for i in R(W)])for j in R(H)];e=sum(r.find(’0?)<0for r in B);D.flip();c+=1\n "
" if c%5<1:\n if k(p,x,y+1)<1:\n if y<1:break\n a+=e and 2**e;n=b=v([r"
" for r in B if~r.find('0')])\n else:y+=1\n");print 'GAME OVER: score %i'%a
Y gracias a Anieto me encuentro con este otro tetris es en Javascript, en más o menos 8 líneas de código:

</body>
