问：

我正在使用一个名为 Topologicpy 的 python 软件库。我有 7 个对象。每个人都有一本字典。每个字典都有一个名为“brepStringType”的键，其值为“Face”或“Cell”。我想删除 brepStringType “Cell” 的对象，以便我可以对“Faces”进行进一步的操作。我想概括一下这一点，以便它可以在具有更多面孔和单元格的脚本上工作。

# Retrieve the vertex object list using Graph.Vertices
objectslist = Graph.Vertices(g)
print(type(objectslist))
print(objectslist)

这将返回以下内容

<class 'list'>
[<topologic.Vertex object at 0x00000180C8AA69B0>, <topologic.Vertex object at 0x00000180C8AA6B30>, 
<topologic.Vertex object at 0x00000180C8AA74F0>, <topologic.Vertex object at 0x00000180C8AA74B0>, 
<topologic.Vertex object at 0x00000180C8AA7470>, <topologic.Vertex object at 0x00000180C8AA6DB0>, 
<topologic.Vertex object at 0x00000180C8AA5230>]

for vertexObjects in objectslist: 
    
    d = Topology.Dictionary(vertexObjects)
    keys = Dictionary.Keys(d)
    brepTypeString = Dictionary.ValueAtKey(d, 'brepTypeString')

    print(vertexObjects)
    print(d)
    print(keys)
    print(keys[2])
    print(brepTypeString)
    

返回以下内容

# How do I delete all objects with key-value brepTypeString "Cell"? 
    if brepTypeString == "Cell": 
        print(brepTypeString)
        # del (????)
