菜鸟的递归查找文件python实现，菜鸟递归python,做为一个python学习

做为一个python学习的菜鸟，老师说不停的写代码是最好的学习方式。这次我写的是递归查找文件python实现：具体实现方法如下
1、首先，输入要查找的特定目标文件扩展名，来遍历查找特定扩展名的文件。这里是：eg:python find_file.py txt；
2.之后通过-f来指定将结果写入到特定名称的文件：eg：python -f txt_result txt,否则将结果打印在控制台；
3最后，要在指定要查找的特定扩展名文件后，找到指定查找的根目录：eg：python find_file.py txt /；

python菜鸟新手写的代码，如果有不妥之处，还请高手指正。
