计算总利润

Question

我是python编程的初学者。正在尝试使用numpy软件包来计算杂志发行的总利润。不确定我在哪里犯错，结果放在方括号中。

建议我的错误所在以及如何调试此错误以解决问题。并且我对命令的用法正确吗？

distr = np.array([[0.315, 0.226, 0.289, 0.087, 0.083],
              [560, 530, 389, 202, 278],
              [533, 486, 386, 234, 263]])
order_1 = np.array([[430,430,430,430,430],
                  [380,380,380,380,380]])

probs = np.array([0.315, 0.226, 0.289, 0.087, 0.083])
paper1 = np.array([560, 530, 389, 202, 278])
paper2 = np.array([533, 486, 386, 234, 263])
order1 = np.array([430,380])
price = np.array([1.0,1.15])
price1 = np.array([1.0])
cost = np.array([0.6,0.8])

expected_soldqty1 =(np.minimum(order.reshape((2,1)), distr[1:]))
print ('Expected SOld Qty:' + str(expected_soldqty1))

selling_price = np.dot((expected_soldqty),(price.reshape(2,1)))
print ('Selling_price   :' + str(selling_price))

cost_price= np.sum(np.dot(cost.reshape((2,1)),order_1[0:1]))
print ('Cost Price   :' + str(cost_price))

profit = np.subtract(selling_price,cost_price)
print ('Expected total Profit    :' + str(profit))

---

Result: 

Expected SOld Qty:[[430. 430. 389. 202. 278.]
 [380. 380. 380. 234. 263.]]
Selling_price   :[3611.55]
Cost Price   :3010.0
Expected total Profit    :[601.55]
