python代码正在打印内存地址而不是函数中的数据答案

【问题标题】：python code is printing memory address instead of data from the functionpython代码正在打印内存地址而不是函数中的数据

对于这个问题我完全不知所措，我尝试了在互联网上找到的多个修复程序，我认为这些修复程序可以修复代码，但它仍在打印内存位置而不是数据。我对 python 完全陌生，并试图自学即将到来的编码课程。程序应提示用户房间数量和清洁程度，然后打印每个房间的总成本和总成本。

我们将不胜感激任何解决此问题的帮助。

【问题讨论】：

clean_cost 是一个函数对象。 clean_cost() 是调用该函数的方式。

标签： python memory

【解决方案1】：

您没有调用该函数。当你写-

print('It will cost :', clean_cost, ':per room cleaned.')

它只是打印函数而不是调用它并获取一个值。确保调用该函数。对于您的情况，如下-

print('It will cost :', clean_cost(), ':per room cleaned.')

【解决方案2】：

你必须在这里调用函数：

# Output Phase
    print('It will cost :', clean_cost, ':per room cleaned.')
    print('The total cost of cleaning this space is: ', str(total_clean_cost))

像这样：

 # Output Phase
    print('It will cost :', clean_cost(), ':per room cleaned.')
    print('The total cost of cleaning this space is: ', str(total_clean_cost(room_qty)))

请记住，您需要将room_qty 作为参数添加到您的函数total_clean_cost，而不是像为clean_cost() 那样只添加空括号。
