python实现矩阵乘法

最近刚开始学习python，为啥要学习这门语言呢？因为学校做项目的需要(>^<)。。。要让我写爬虫，我是从http://pymbook.readthedocs.io/en/latest/index.html
这个博客入门的。最近刚学完list，就写了这个矩阵乘法入手。光看不练假把式。编程就是要多动手啊。

n = int(input("enter rows of matrix A:"))
a = []
for i in range(0, n):
a.append([int(x) for x in input("").split(" ")])
m = int(input("enter rows of matrix B:"))
b = []
for i in range(0, m):
    b.append([int(x) for x in input("").split(" ")])

c = []
for i in range(0, n):
    c.append( [sum(a[i][j] * b[j][k] for j in range(0, m)) for k in range(0, len(b[0]))])
print("Here is answer:")
print("-"*10*n)
for x in c:
    for y in x:
        print("%4d" % y, end=" ")
    print("\n")
print("-"*10*n)
