Question

初学者在这里使用python。

刚写了一个简单的程序，但输出不正确。我必须遗漏一些非常基本的东西。

示例输入数据：

Prody
1000000
3000

输出结果为：

Hi Prody
The property price is:  1000000
The estimated rental cost for the property is:  3000
The price to rental ratio for the property = 27
This is an expensive property.

但输出应该是：

Hi Prody
The property price is:  1000000
The estimated rental cost for the property is:  3000
The price to rental ratio for the property = 27
This property is a bit expensive.

怎么了？

谢谢！

代码：

information = {'name': '0', 'cap': 0, 'rent': 0}

print "First you need to provide some information."
information['name'] = raw_input("What is your name?")
information['cap'] = raw_input("What is the cost of the property?")
information['rent'] = raw_input("What is the estimated rent for the property?")

print "\n"
print "Hi", information['name']
print "The property price is: ", information['cap']
print "The estimated rental cost for the property is: ", information['rent']
print "\n"

class Property(object):

    def enter(self):
        pass

class Overpriced(Property):
    def testprice(self):
         print "The price to rental ratio for the property =",
                int(information['cap']) / (12 * int(information['rent']))

        if tprice > 40:
            print "This is an expensive property."
        elif (tprice > 25) and (tprice < 40):
            print "This property is a bit expensive."
        else:
            print "Testing."

tprice = Overpriced()
tprice.testprice()

感谢您的评论，将最后一部分更改为：

class Overpriced(Property):
    def testprice(self):
        rental_ratio = int(information['cap']) / (12 * int(information['rent']))
        print "The price to rental ratio for the property =", rental_ratio

        if rental_ratio > 40:
            print "This is an expensive property."
        elif (rental_ratio > 25) and (rental_ratio < 40):
            print "This property is a bit expensive."
        else:
            print "Testing."

tprice = Overpriced()
tprice.testprice()

Answer 1

你计算了这个值并打印出来，但是后来你没有使用它。此修复程序将使其工作：）

class Overpriced(Property):
def testprice(self):
     computed_price = int(information['cap']) / (12 * int(information['rent']))
     print "The price to rental ratio for the property =",computed_price


    if computed_price > 40:
        print "This is an expensive property."
    elif (computed_price > 25) and (computed_price < 40):
        print "This property is a bit expensive."
    else:
        print "Testing."

tprice = Overpriced()
tprice.testprice()

Python程序产生错误的输出
