The first time to write code in Python, there are some habits, such as if, else, for, def to add:, if a new compilation tool may be better, otherwise you can only see the error message each time you run. It also benefits from the fact that there is no need for each statement input, that you do not need to enter {}, and that by indenting to understand semantics (indentation is semantics), the function is very powerful when traversing the directory. For Root,dirs,files in Os.walk (path), When you need a separate file name can be directly from files to fetch, need full path with foot join one is OK, do not need to write recursively traverse directory, do not need to detach the file name from the full path ^_^ In fact, the syntax of Python is not very clear, Just read someone else write code snippets, write when one side according to their own understanding of writing, encountered errors on the search Help and Baidu, although play to the night nearly 11 points, or feel very good
