Question

我真的不太确定如何在python中最好地接近以下内容...... 我知道我想要什么，并且知道我的想法，但我不知道我的想法是否是我正在寻找的最佳方法。

"Name":"path",contains[]
"Folder":"C:/blah/blah/folder",contains["file1","file2","file3"]

喜欢

things={}
things["Folder"]="C:/blah/blah/folder" AND contains["file1","file2","file3"]

以便它可以像：

一样使用

for folder,path,contents in things.iteritems():  
    print("%s @ \"%s\" containing:\n\t")%(folder,path)  
    for file in contents:  
        print("%s\n\t")%(file)

如何将内容添加到内容中，例如

content.append(blah)

任何帮助将不胜感激！感谢。

Answer 1

这样的东西？

>>> d = {}
>>> d["Folder"] = ["C:/blah/blah/Folder", ["file1","file2","file3"]]
>>> d["more"] = ["/home/mydir", ["file1","file2","file3"]]
>>> d["Folder"][0]
'C:/blah/blah/Folder'
>>> d["Folder"][1]
['file1', 'file2', 'file3']
>>> d["Folder"][1].append("file4")
>>> d["Folder"][1]
['file1', 'file2', 'file3', 'file4']
>>> for entry in d:
...     d[entry][1].append("newfile")
...
>>> d
{'Folder': ['C:/blah/blah/Folder', ['file1', 'file2', 'file3', 'file4', 'newfile']],
 'more': ['/home/mydir', ['file1', 'file2', 'file3', 'newfile']]}

我认为你正在寻找一个嵌套字典：

things = {"Folder" : {"path" : "C:/blah/folder", "contents" : ["file1", "file2"]},
          "Directory" : {"path" :"C:/foo/dir", "contents" : ["fileX", "fileY"]}}
for folder, info in things.iteritems():
  print("%s @\"%s\" containing:\n\t")%(folder, info["path"])
  for file in info["contents"]:
    print("%s\n\t")%(file)

Answer 3

things = {}
things["Folder"] = ("C:/blah/blah/folder", ["file1","file2","file3"])

for folder, (path, contents) in things.iteritems():
    print("%s @ \"%s\" containing:\n\t")%(folder,path)  
    for file in contents:  
        print("%s\n\t")%(file)

尝试使用字典创建一些东西但是丢失了
