Solution in Python3 (judge verdict: Accepted)

judge=True
while judge:
    N=list(map(int,input().split()))
    if N[0] + N[1] == 0:
        judge = False
    else :
        for i in range(0,N[0]):
            for j in range(0,N[1]):
                print("#",end="")
            print("\n",end="")

        print("\n",end="")
