less文件批量转换为css

 3 def auto_less_to_css(file_dir):
 4     # 获取当前目录下所有的css文件路径
 5     all_whole_path_files = []

10                     file_info = [root+‘/‘, file]
11                     all_whole_path_files.append(file_info)

21         try:
22             result = os.popen(new_command).readlines()
23             if len(result) == 0:
24                 print(less_file_path_file, "已经转换为", css_file_path_file)
25         except Exception as e:

python 写脚本很方便 此脚本功能为将某文件夹内的所有.less文件转换为.css文件  此脚本来源于js 木子昭

理论上利用os.walk()便利所有文件夹路径 文件夹名称 文件名称

字符串拼接和切片

加上os.popen(new_command).readlines() 命令行操作  

可以执行所有的的批量文件转换功能（前提是已经安装了转换器，可以cmd命令调用）
