Method One: Using the function os.walk()

os.walk()will return ternary tuples(dirpath, dirnames, filenames)
dirpath: Root Path (String)
dirnames: All directory names under path (list)
filenames: All non-directory file names under path (list)

The directory name and file name are not added to the root path, so a full path is required to connect the directory name or file name to the root path.
Example:

import osroot = "C:\\dir"for dirpath, dirnames, filenames in os.walk(root):    for filepath in filenames:        print os.path.join(dirpath, filepath)

Method Two: Using the function os.listdir() , os.path.isdir()os.path.isfile()

os.listdir()You can list all file and directory names under the path, but do not include the current directory . , the parent directory, .. and the files under subdirectories.
os.path.isfile()And os.path.isdir() determine if the current path is a file or directory

Example:

import osdef listDir(rootDir):    for filename in os.listdir(rootDir):        pathname = os.path.join(rootDir, filename)        if (os.path.isfile(filename)):            print pathname        else:            listDir(pathname)
