感觉写的还不错
x = int(input())
y = int(input())
z = int(input())
A = []
B = []
for i in range(x):
A.append(list(map(int,input().split(' '))))
for i in range(y):
B.append(list(map(int,input().split(' '))))
C = []
for i in range(x):
C.append([])
for j in range(z):
result = 0
for k in range(y):
result += A[i][k]*B[k][j]
C[i].append(result)
for i in C:
print(*i)
