Question

请注意我最近才开始学习Python，所以寻找一些非常基本的代码。

我有一个程序需要计算三种形状（立方体，金字塔和椭圆体）的体积，这很容易。问题是，在测试者（用户）为所有三个形状计算了许多不同的体积之后，程序必须输出不同形状的列表以及为每个形状计算的所有体积。

为了更好地解释，假设用户计算3个立方体，2个金字塔和5个椭圆体的体积。当用户键入“退出”而不是新形状时，程序必须输出：

“你已经到了会议的最后阶段。每种形状的计算体积如下所示：立方体:(计算的所有卷的列表）金字塔:(计算所有卷的清单） Ellipsoid :(计算的所有卷的列表）“

提前谢谢！对于使用Pycharm Edu 3.0.1和Python 3.5.7的记录

我会用3个列表来做这件事。因此，在while(True) - 循环之前，您需要定义列表：

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

然后在3卷的主要功能中，您可以将结果添加到列表中。例如，对于金字塔，您将拥有以下主要功能：

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))

现在，每次用户计算音量时，它都会被添加到3个列表中的一个。作为最后一步，您可以在用户想要退出时打印列表：

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

如果你想让列表格式化，你可以这样做：

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

如何列出计算的所有输入？
