python生成树目录
【1】代码
import sys from pathlib import Path class DirectionTree(object): """生成目录树 @ pathname: 目标目录 @ filename: 要保存成文件的名称 """ def __init__(self, pathname='.', filename='tree.txt'): super(DirectionTree, self).__init__() self.pathname = Path(pathname) self.filename = filename self.tree = '' def set_path(self, pathname): self.pathname = Path(pathname) def set_filename(self, filename): self.filename = filename def generate_tree(self, n=0): if self.pathname.is_file(): self.tree += ' |' * n + '-' * 2 + self.pathname.name + '\n' elif self.pathname.is_dir(): self.tree += ' |' * n + '-' * 2 + \ str(self.pathname.relative_to(self.pathname.parent)) + '\\' + '\n' for cp in self.pathname.iterdir(): self.pathname = Path(cp) self.generate_tree(n + 1) def save_file(self): with open(self.filename, 'w', encoding='utf-8') as f: f.write(self.tree) if __name__ == '__main__': dirtree = DirectionTree() # 命令参数个数为1,生成当前目录的目录树 if len(sys.argv) == 1: dirtree.set_path(Path.cwd()) dirtree.generate_tree() print(dirtree.tree) # 命令参数个数为2并且目录存在存在 elif len(sys.argv) == 2 and Path(sys.argv[1]).exists(): dirtree.set_path(sys.argv[1]) dirtree.generate_tree() print(dirtree.tree) # 命令参数个数为3并且目录存在存在 elif len(sys.argv) == 3 and Path(sys.argv[1]).exists(): dirtree.set_path(sys.argv[1]) dirtree.generate_tree() dirtree.set_filename(sys.argv[2]) dirtree.save_file() else: # 参数个数太多,无法解析 print('命令行参数太多,请检查!')
【2】测试命令
同样可以使用以下三条命令进行测试:
-
python dirtree.py
:打印当前目录的目录树; -
python dirtree.py E:\Programming\Python\applications
:打印指定目录的目录树; -
python dirtree.py E:\Programming\Python\applications dirtree.txt
:打印指定目录的目录树并保存成文件
