我想使用NumPy包在Python中垂直连接两个数组,但是我需要一个不同的输出。
我有两个列表
a=[1,2,3]
b=[7,8,9]
我写这是为了解决问题
a1 = np.array(a)
a2 = np.array(b)
np.vstack((a1,a2))
我的输出是
[[1 2 3]
[7 8 9]]
但是我需要这样的输出
array([[1, 2, 3],
[7, 8, 9]])
我想念什么?谢谢
答案 0 :(得分:0)
您的结果正确是x = 0
cb = 25000
a = 50000
unpaid = cb-x # unpaid balance
inc = unpaid*(a/12) # increment
def mintha (x):
'''
x is the minimum payable per month to pay off debt (round to tenth)
'''
totalPay = unpaid + inc # total credit balance, including the
# interests
if (12*x - totalPay) >= 0:
return round(x)
else:
totalPay = unpaid + inc
return round(totalPay)
print(mintha(3000))
#Output:
104191667
。要查看此内容,您需要其repr
而不是打印输出:
np.ndarray
