第一题：

顺时针输出矩阵元素：

def printMatrix(matrix):
    res = []
    while matrix:
        res += matrix.pop(0)
        if matrix and matrix[0]:
            for row in matrix:
                res.append(row.pop())
        if matrix:
            res += matrix.pop()[::-1]
        if matrix and matrix[0]:
            for row in matrix[::-1]:
                res.append(row.pop(0))
    return res
if __name__=='__main__':
    a = raw_input()
    print a
    result = []
    b = a.split('],[')
    print b
    for i in range(len(b)):
        if i == 0:
            t = b[i].lstrip('[[')
            cat = t.split(',')
            result.append(cat)
        elif i == len(b) - 1:
            t = b[i].rstrip(']]')
            cat = t.split(',')
            result.append(cat)
        else:
            cat = b[i].split(',')
            result.append(cat)
    print ','.join(printMatrix(result))

# [[2,3,6],[5,5,9],[3,6,9]]
#2,3,6,9,9,6,3,5,5

运行结果：

蓝瘦。。。。。。。就剩一句了，没写到笔试网页上！o(╥﹏╥)o
