Bagaimana cara mengubah jalur file menjadi tampilan pohon?

Dari Python, Anda dapat membuat JSON yang Anda inginkan sebagai berikut (perhatikan bahwa indentasi dan pengurutan tidak diperlukan jika Anda hanya mengirimkan JSON secara keseluruhan, tetapi keduanya membuat output dapat dibaca untuk debugging):

import collections
import json

myfiles = '''
    a/b/c/d/e/file1
    a/b/c/d/e/file2
    a/f/g/h/i/file3
    a/f/g/h/i/file4
'''

# Convert to a list
myfiles = myfiles.split()


def recursive_dict():
    """
    This function returns a defaultdict() object
    that will always return new defaultdict() objects
    as the values for any non-existent dict keys.
    Those new defaultdict() objects will likewise
    return new defaultdict() objects as the values
    for non-existent keys, ad infinitum.
    """
    return collections.defaultdict(recursive_dict)


def insert_file(mydict, fname):
    for part in fname.split('/'):
        mydict = mydict[part]

    # If you want to record that this was a terminal,
    # you can do something like this, too:
    # mydict[None] = True

topdict = recursive_dict()
for fname in myfiles:
    insert_file(topdict, fname)

print(json.dumps(topdict, sort_keys=True,
                indent=4, separators=(',', ': ')))

Kode ini menghasilkan output berikut:

{
    "a": {
        "b": {
            "c": {
                "d": {
                    "e": {
                        "file1": {},
                        "file2": {}
                    }
                }
            }
        },
        "f": {
            "g": {
                "h": {
                    "i": {
                        "file3": {},
                        "file4": {}
                    }
                }
            }
        }
    }
}
