在任意深度的嵌套字典上行走/迭代(字典代表目录树)

def iterate_nested_dict(d, path=None):
    if path is None:
        path = []

    for k, v in d.items():
        if isinstance(v, dict):
            yield from iterate_nested_dict(v, path + [k])
        else:
            yield path + [k], v


nested_dict = {
    'a': {
        'b': {
            'c': 1
        },
        'd': 2
    },
    'e': 3
}

for path, value in iterate_nested_dict(nested_dict):
    print(f"Path: {path}, Value: {value}")

Path: ['a', 'b', 'c'], Value: 1
Path: ['a', 'd'], Value: 2
Path: ['e'], Value: 3
