Python file related applications and how to write code, I believe that many inexperienced people do not know what to do, so this paper summarizes the causes of the problem and solutions, through this article I hope you can solve this problem.

Python file

Import os import os.path

Os,os.path contains most file access functions, so introduce Python files first. Please modify this path according to your actual situation

Rootdir = "d:/download" for parent, dirnames, filenames in os.walk (rootdir): # case 1: for dirname in dirnames: print ("parent is:" + parent) print ("dirname is:" + dirname) # case 2 for filename in filenames: print ("parent is:" + parent) print ("filename with full path:" + os.path.join (parent, filename))

Knowledge points:

Os.walk returns a triple. Where dirnames is the name of all folders (excluding paths) and filenames is the name of all files (excluding paths). Parent represents the parent directory. Case1 demonstrates how to traverse all directories. Case2 demonstrates how to traverse all Python files.

Os.path.join (dirname,filename):

Change shapes like "/ a/b/c" and "d.java" to / a/b/c/d.java ".
