X = [['A', 'B', 'C'], ['A', 'B', 'D'],['W','X'],['W','Y','Z']]
d = {}
for path in X:
current_level = d
for part in path:
if part not in current_level:
current_level[part] = {}
current_level = current_level[part]
这给我们留下了d {'A': {'B': {'C': {}, 'D': {}}}, 'W': {'Y': {'Z': {}}, 'X': {}}}。包含空字典的任何项目都是文件或目录。
