根据题目描述照着写就行了，最后一行打印不用等矩阵C全部计算完再输出，
每一行计算完之后就可以输出该行了
x = int(input())
y = int(input())
z = int(input())
A,B = [],[]
for _ in range(x):
A.append(list(map(int,input().split())))
for _ in range(y):
B.append(list(map(int,input().split())))
C = [[0]*z for _ in range(x)]
for i in range(x):
for j in range(z):
for k in range(y):
C[i][j]+=A[i][k]*B[k][j]
print(' '.join(list(map(str,C[i]))))
