计算总楼层尺寸（Python）

Question

我需要计算一下总的楼层面积。它首先询问房间的数量（所有房间都是矩形的），然后使用for循环询问每个房间的长度和宽度。以下是我的代码（python）：

norooms = int(input('How many rooms does the floor have?'))
length = dict()
width = dict()
for i in range(norooms):
    length[i] = input('what is the length of room?')
    width[i] =input('what is the width of room?')
    print('that was room number:',i+1)

现在我得计算一下地板的总数。我能帮个忙吗？在

Answer 1

norooms = int(input('How many rooms does the floor have?'))
length = dict()
width = dict()
for i in range(norooms):
    length[i] = input('what is the length of room?')
    width[i] =input('what is the width of room?')
    print('that was room number:',i+1)
total=0
for i in range(norooms):
    total += float(length[i])*float(width[i])

print 'total is:' ,total

如果它在Programming Exchange中，我建议改为使用以下代码：

^{pr2}$

Answer 2

使用numpy可以很快解决这个问题。如果你将来要做类似的事情，花点时间学习图书馆也许是值得的。在

不管怎样，给你：

import numpy as np

no_rooms = int(input('How many rooms does the floor have?'))

length = np.empty(no_rooms)
width = np.empty(no_rooms)

for i in range(no_rooms):
    length[i] = input('what is the length of room?')
    width[i] = input('what is the width of room?')
    print('that was room number:', i+1)

print('total is: ' + str(np.dot(length, width)))

你知道怎样计算给定房间的面积？对所有房间都这样做，然后计算总数。还要注意，目前房间的长度和宽度仍然是字符串。在
