编写程序:输入长方体的长.宽.高.求长方体的体积，要求输出体积具体值时有提示语“长方体的体积”以实数的形式输出，输出时，保留宽度为6位，不足的用0补齐，小数点后面保留三位小数
class Cuboid:
def __init__(self, length, width, high):
# data must > 0
if length <= 0:
raise ValueError("length <= 0!")
if width <= 0:
raise ValueError("width <= 0!")
if high <= 0:
raise ValueError("high <= 0!")
# save the data
self.__length = length
self.__width = width
self.__high = high
# caculate and save the surface area and volume
self.__area = float(2 * (self.__length * self.__width + self.__width * self.__high + self.__high * self.__length))
self.__volume = float(self.__length * self.__width * self.__high)
def get_area(self):
return self.__area
def get_volume(self):
return self.__volume
if __name__ == '__main__':
length = float(input("Please enter the length: "))
width = float(input("Please enter the width: "))
high = float(input("Please enter the high: "))
TestCuboid = Cuboid(length, width, high)
print("Surface area is: ", TestCuboid.get_area())
print("Volume is: ", TestCuboid.get_volume())
long = float(input('输入长方体的长：'))
width = float(input('输入长方体的宽：'))
height = float(input('输入长方体的高：'))
print('长方体的体积:%06.3f'%(long*width*height))长度为6，三位小数
只需要把公式带进去就行v=abc
Height = float(input('>'))
Long = float(input('>'))
Width = float(input('>'))
Result = (Height*Width*Long)
print(f"长方体的体积为{Result}.")代码如上，万望采纳。
