尝试添加两个以字符串形式输入的数字矩阵，然后显示解决方案，但 stdin 和 stdout 出现问题

Question

使用标准输入输入两个矩阵然后在标准输出中显示结果是一项编程任务。当程序运行良好时，我经常发现运行时错误或没有标准输入或标准输出显示。

这是我添加两个矩阵的代码。

       """The constraint is the numbers will be entered only without any 
          string to be seen on console and also that to be in the same
          fashion being each number input separated by a white space."""
          import sys

            def main():

            num1 = []
            num2 = []

            rc1 = raw_input().split(' ')
            rc1_arr = [int(z) for z in rc1]
            r1 = rc1_arr[0]
            c1 = rc1_arr[1]
            while(r1 != 0):
                    mat1 = raw_input().split(' ')
                    arr1 = [int(z1) for z1 in mat1]
                    num1.append(arr1)
                    r1=r1-1

            rc2 = raw_input().split(' ')
            rc2_arr = [int(z) for z in rc2]
            r2 = rc2_arr[0]
            c2 = rc2_arr[1]
            while(r2 != 0):
                    mat2 = raw_input().split(' ')
                    arr2 = [int(z2) for z2 in mat2]
                    num2.append(arr2)
                    r2=r2-1

            for i in range(max(rc1_arr[0],rc2_arr[0])):
                 for j in range(max(rc1_arr[1],rc2_arr[1])):
                     su = num1[i][j]+num2[i][j]
                     sys.stdout.write(str(su))
                     sys.stdout.write(" ")
                 sys.stdout.write("\n")

        main()

       """ while running in idle it looks like this
       ##The input part is:

请帮忙。

你可能对缩进有一些问题...我没有碰线（除了调整缩进，它按预期工作！）

#!/usr/bin/env pyhton2

def main():

    num1 = []
    num2 = []

    rc1 = raw_input().split(' ')
    rc1_arr = [int(z) for z in rc1]
    r1 = rc1_arr[0]
    c1 = rc1_arr[1]
    while(r1 != 0):
        mat1 = raw_input().split(' ')
        arr1 = [int(z1) for z1 in mat1]
        num1.append(arr1)
        r1=r1-1
