I have been trying to use a list of paths to implement a TreeView on a website with Material UI components.

I used the code found in the TreeView Component in MUI here https://mui.com/material-ui/react-tree-view/#rich-object

But I only have a list of paths like this:

dirs = ['path/to/file/file1.txt',
    'path/to/file/file2.txt',
    'path/to/another_file/file3.txt']

And I wanted to reach a structure that looks like this

{'path': {'to': {'files12': ['file1.txt',
                             'file2.txt']},
                 'file3':    'file3.txt'}
         }
}

In order to use that with my function in React which I somehow got to work until it broke at the leaf node, because the dictionary I was using was the one created from here https://stackoverflow.com/a/58917078/9790150 which reads the leaf nodes forever and reached max call stack size.

Below is the best I could get my function inside my page to work

 const renderTree= (my_dict) => (
<TreeItem key={Object.keys(my_dict)[0]} nodeId={Object.keys(my_dict)[0]} label ={Object.keys(my_dict)[0]}>
    {Array.isArray(Object.values(my_dict))
      ? Object.entries(my_dict).map((node) => renderTree(node))
      : null}
</TreeItem>
);

. Note: The above function is not complete. It's just where I've got until now.

I can provide further clarification as needed because I don't understand things fully myself yet.

So TL;DR

I either need a way to turn a list of paths into the structure format found in the TreeView example which looks like this:

const data = {
  id: 'root',
  name: 'Parent',
  children: [
    {
      id: '1',
      name: 'Child - 1',
    },
    {
      id: '3',
      name: 'Child - 3',
      children: [
        {
          id: '4',
          name: 'Child - 4',
        },
      ],
    },
  ],
};

Which feels too complicated to do in Python or Javascript since I can most likely make a function that works with the 2nd option ->

A way to turn it into a dictionary of dictionaries as shown above in my desired output

Any suggestions on how I should go about creating what I want in an easier manner are appreciated.
