如何列出所有計算的輸入？

Question

請注意我最近纔開始學習Python，所以尋找一些非常基本的代碼。

我有一個程序需要計算三種形狀（立方體，金字塔和橢球體）的體積，這很容易。問題是，在測試人員（用戶）已經爲所有三種形狀計算了許多不同體積後，程序必須輸出不同形狀的列表以及它爲每個形狀計算的所有體積。

爲了更好的解釋，比方說用戶計算3個立方體，2個金字塔和5個橢圓體的體積。當在「退出」，而不是一個新的形狀，然後程序的用戶類型必須輸出：

「你已經來到會議結束 計算每個形狀的卷如下： 立方：（所有體積清單計算） 金字塔:(所有體積清單計算） 橢圓體:(所有體積清單計算）「

謝謝您提前！ 對於使用Pycharm埃杜3.0.1和Python 3.5.7

    print ("The volumes calculated for each shape are shown below.") 
    print ("Cube: ") #what I need to find out 
    print ("Pyramid: ") #same as above 
    print ("Ellipsoid: ") # again 
else:                      
    print ("That is not a proper shape") 
    continue

我會做這個用3只列出了記錄。所以，你的while(True)之前-loop您定義的列表：

cubeList = [] 
pyramidList = [] 
ellipsoidList = [] 

然後在你的3卷的主要功能，你可以將結果添加到列表中。例如，對於您將有以下主要功能金字塔：

def main(): 
    result2 = round((pyramidVolume(baseLength,heightLength)),2) 
    pyramidList.append(result2) 
    print ("A pyramid with base {} and height {} has a volume {}".format(baseLength,heightLength,result2)) 

現在，每個用戶計算量的時候，就會被添加到3所列出之一。作爲最後一步，你可以只打印清單，而用戶想退出：

print ("Cube: {}".format(cubeList)) 
print ("Pyramid: {}".format(pyramidList)) 
print ("Ellipsoid: {}".format(ellipsoidList)) 

如果你想有很好的清單格式化，你可以做這樣的事情：

cs = "" 
for ind,el in enumerate(cubeList): 
    cs += "Shape {} has volume {}".format(ind,el) 
print ("Cube: {}".format(cs))
