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。
